  1. Annual DIY-ers 7:45pm Wednesday 11th December Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 It's that time of the year again when the DIY members get to show off their Hi-Fi projects at the December General Meeting. This year we have two distinct systems to listen to, one based around a full range speaker and the other a conventional 3way box design. Our first system is a 'one man band' of DIY projects. Mark H has been busy over the year building a number of electronic components. Starting off with the front end, a 'Raspberry Pi' music server running into a homemade DAC, using the AK4497EQ DXD chip. The Grand Fidelity tube preamp in a SRPP (active load), takes care of the analogue signal with its pair of gorgeous looking 6SN7 sphere valves. The amplifier of choice for the night will be his 180 Watt compact Tripath Class D power amp in a retro looking wood Cheek enclosure. The speakers are also built by Mark, using a single full-range driver the 'Mark Audio' 12P (8") in a slimline mini tower enclosure. With an efficiency of 92dB, these speakers should easily fill the Willis room with plenty of sound. Our second system for the night is based around the classic looking JBL L 100's. With a 12inch base driver in a sealed box, the speaker comprises of a 4inch Aluminium Midrange from SB Acoustics and a 1inch fabric dome tweeter. All mitre cuts and routering was professionally done to pre finished boards. The idea being, something easy to put together, and no complicated or expensive finishing process. The speakers will be driven with another Class D power amp based on the 100W Sure Electronics module, with a valve pre amp using a pair of 6j1's. Is there a theme here? Source material for the night will be from a SACD player. Each system will have an allotted time of 45minutes, to give each presenter plenty of time to explain their gear as well as play some music. Looks like we will have an interesting evening. Nick Karayanis, Program Co-Ordinator. Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  2. Rockian Trading and Osborn Loudspeakers 7:45pm Wednesday 20th November Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 Once again we thank Greg and Yvonne Osborn for providing superb audio equipment to demonstrate some of the recordings we distributed in 2019. As usual Beverley's bazaar will have a selection of recordings for sale to MAC members at special prices, and some particular bargains will be offered from the Rockian Trading catalogue. As many MAC members know we recorded and produced our own CD of The Delmatics rock and roll band in June and we were privileged to play some of the music live to the members at the July meeting. Although the band members all enjoyed the evening they thought it was the most demanding performance we have made in a very long time. Instead of playing to a room full of dancing people singing along with the familiar songs, we were on stage before a seated audience of audio and record enthusiasts. It was like, "Being under the microscope," according to one band member. It was fun, thank you. We have almost sold enough CDs to cover our production costs, so further purchases by MAC members will be most welcome And, although it may not be immediately obvious, The Delmatics is an audiophile album. Put the CD on a good, big system, turn it up loud and enjoy what The Delmatics actually sound like live. (And perhaps you can also dance a little.) As always there have been changes in our industry. Mobile Fidelity have shifted their recorded music output from quantity to quality. Instead of releasing ten or more 180gram LPs and SACDs per annum, this year they have produced three 180gram LPs, about five SACDs, and three One-Step double LP Box Sets. Time at the quality pressing plants has become precious so they are trying to make the best of a limited resource. We are waiting, impatiently for the anticipated release of four more Dire Straits albums. Cala Records sold-out to another British label that already have distribution in Australia. This meant no more new releases from the label. Cala Records founder, chief conductor and CEO, Geoffrey Simon, has partnered with his brother to return to the Simon family tradition of commercial property building and development. Geoffrey is the son of Leo Simon, the founder of LU Simon Builders Pty Ltd. NMC continue to supply us with contemporary classical works from The United Kingdom. Besides their own brand they also provide a number of other small independent, modern labels. Some challenging material and some rewarding gems on CD, and recently on LP and compact cassette. Opus 3 Records have released a few new recordings and re-masters from past efforts. These days Jan-Eric is kept busy making and distributing his "Open- Reel Tapes." This is not a format we have really embraced. Open Reel Tape is too limited in Australia and too expensive for normal distribution. Almost all reel-to-reel tape is purchased direct from the producer by the end user. Thankfully ATMA Classique record and promote a growing list of great Canadian artists and repertoire. Their releases can be very interesting because the Quebecois are reputed to be more French than the French, and the Impressionist composers are interpreted with great passion. Recent releases from Reference Recordings have provided me with a number of what I classify as "goose-bump" moments. Their recent double LP release of The Dallas Winds performing "John Williams at the Movies" has several such moments and their SACD of the Hermitage Trio performing Rachmaninoff piano trios is passionate Russian virtuosos performing passionate Russian repertoire. And, Reference Recordings have provided me with another "Organ Recording." Several of their releases on Fresh! from RR have also provided some interesting and rewarding listening. Stockfisch Records from Germany continue to produce interesting new recordings released on both SACD and quality LP. They have also exposed two more "Analog Pearls," gems from the Stockfisch Records tape vaults. Of particular interest to me is the latest collection of Allan Taylor songs released on his second In The Groove LP. This is of particular interest to me because I recently uncovered, in my own LP library, Taylor's first recording from 1971 titled "Sometimes." His beard is gone, his hair colour has faded and his tone has dropped a full octave. I thank the club for inspiring me to spend the best part of a week to playing the best recordings released through Rockian Trading this year. I hope to provide MAC members with some interesting listening and commentary. Rockian Trading continues to supply Mobile Fidelity, Chesky Records, NMC Records, ATMA Classique, Reference Recordings and Opus 3 Records through stores like Readings Books and Music. We also provide audiophile labels to specialist stores like Quality Records in Malvern, Greville Records in Prahran and Audiophile Reference Recordings in Cheltenham, as well as to hi-fi stores like Tivoli Hi Fi in Hawthorn, Audiophile in Heidelberg Heights, Audio Trends in Ringwood and a number of other specialist stores all around Australia.

  3. B&W 702 S2 presented by 'The Audio Experts' 7:45pm Wednesday 18th September Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 It has been over two years since the club was presented with a demonstration from the top-of-the-range B&W speakers, the 800 D3's. Back then, we were introduced to a lot of new innovations that has re-invented this model. In keeping with B&W's philosophy of trickle down technology, the new 702 S2 features many of the new technology from the 800 series. This month we have 'The Audio Experts' aka Whatmough Audio, presenting at the MAC the new 702 S2 floor standing speaker, and its matching bookshelf model, the 705 S2. The speakers will be demonstrated with the same amplifier from PASS LABS the Model 60, while a Marantz KI Pearl SACD player will be playing the tunes. B&W has used its new 'Continuum' midrange cone in the 700 series, replacing the old yellow coloured Kevlar design, and have included the 'tweeter-on -top' technology seen on the 800 series. Sitting in its own aluminium machined pod, the 25mm 'Carbon Dome' tweeter is decoupled from the cabinet. The 702 S2 is a conventional rectangular box that houses a 150mm Continuum FST Midrange driver that is also decoupled from the main box. A set of three 165mm Aerofoil drivers look after the bass frequencies. Like the siblings in the 700 series, the 705 S2 features the new carbon tweeter dome that is more rigid than its previous model, with its first breakup mode now reaching out to 47 Khz. Around the back is the B&W characteristically 'dimpled' reflex port. Supplied with the speakers is a pair of foam bungs (full or half) to accommodate various room placements. The main 165mm mid/bass driver is the new silver coloured Continuum design, said to reach down to 45Hz. With a number of significant upgrades to the new 702/705 models, they offer a taste of the 800-series sound without spending serious money. Will you be putting them on your Christmas list?

  4. Hulgich Audio & Holton Precision Audio 8pm Wednesday 21st August Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month we have two interstate companies joining forces to present their Hi Fi products at the MAC. Both have exhibited together at the Melbourne International Hi Fi Show, winning "Best of Show Overall" for 2017 as well as "Best New Comer". Hulgich Audio is a new speaker company based in Adelaide headed by Nicolas Hulgich (pronounced Eu-Lich), who has spent more than twenty years in both Australia and his native Argentina building speakers with a variety of designs. He will be presenting to the club his statement speaker the 'Duke', with his in-house FTM (Feel The Music) speaker cable and interconnects. The 'Duke' is a 3-way floor stander designed as a dual enclosure. The upper enclosure houses a 1.2 inch dimple dome tweeter, and a 6 inch midrange made of papyrus fibres. The lower bass enclosure is a ported design that houses a 10 inch woofer also made of papyrus fibres. Hulgich has designed the 'Duke' to have a huge sweet spot and a large sound stage. By applying 'Low Diffraction Baffle Technology' (LDBT) that insures a smooth frequency response whether sitting off or on axis, and 'Coherent Sound Technology'( CST) which provides driver time alignment and phase integration. Nicolas will be playing his music with a modified OPPO 103 Multi-disc player and a AudioGD R8 Ladder Dac. Amplification is provided by Holton Precision Audio. Based in northern Tasmania, Anthony Holton has been designing and building high end amplifiers that have been demonstrated internationally at the 2018 Paris and Munich Hi-Fi Shows Anthony will be demonstrating two stereo amplifiers on the night, the Holton One-Zero-Zero Supreme (2x120W into 8 Ohms), and the Five-Zero-Zero Supreme (2x500W into 4 Ohms) with the matching Gain Block One Preamp. On static display will be a Phono Pre, while a 'DC Blocker One' will be used to look after the AC mains. This audio grade conditioner removes DC and filters the noise from the mains. With two presenters for the night, we are certainly going to have twice the value when it comes to sound quality. Not to be missed. Nick Karayanis, Program Co-Ordinator.

  5. Mark Doehmann and Tivoli Hi-Fi Presents 8pm Wednesday 20th March, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month's Melbourne Audio Club meeting will be a collaboration between two presenters. Mark Doehmann the turntable engineer / designer and Tivoli Hi-Fi, Melbourns longest running high-end retail outlet. Both will have a system to demonstrate from their portfolio of hi-fi products. Mark is best known for his high-end turntable designs, having broken new ground in class leading performance by pushing the envelope and challenging the status quo. He has a well-respected track record for innovation and design for both turntables and tonearms. He will present on the new features and sounds of his Helix 1 and model 2 turntable. Ypsilon Audio is a brand that has established it's self in the high-end scene, which Mark has introduced to the Australian market. There latest product the Phaeton, is an integrated hybrid design with a single-ended Class A performance with the power of a push-pull, at 110W into 8 ohms. Accompanying the amplifier will be a pair of German Physiks Omni direction speakers. The second system from Tivoli Hi-Fi will also feature a pair of Omni Directional speakers. The brand is well known for its futurist looking active loudspeakers; these will be from B&O. At the time of this article, Tivoli was still finalising which B&O model they will bring on the night. They will have a music server from Cocktail Audio, in fact two models the X30 and the X45, a streamer and CD ripper for us to listen too. The Hi -Fi industry comprises a large diversity of people, who are pursuing their passion to improve our audio experiences; this month's meeting will be a night not to be missed.

  6. The ATC SCM19A Active Speaker 8pm Wednesday 20th February, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 The Acoustic Transducer Company, ATC for short, is one of a handful of pro-audio companies to have crossed over successfully into the Hi Fi arena. The company was founded back in 1976 by Billy Woodman, an Australian acoustician who developed the famous 3 inch soft dome mid-range driver for professional monitor speakers. Many audiophiles would be very familiar with the domestic range of ATC speakers, with numerous reviews in many magazines. JAG Imports will be presenting at the club the latest active speaker from the new 'Entry Series', the SCM 19A. The least expensive active floorstander in the range, this two way model stands just under a meter high and carries a 182 Watt power pack that is installed in the bottom half of the tower. The 150mm Mid/Bass driver is powered with 150 watts while the 25mm Soft Dome Tweeter receives 32 watts. The Mid/Bass employs ATC's new 'ground-breaking' Super Linear Technology, said to reduce third harmonic distortion by 10-15dB between 100Hz and 3KHz. The tweeter employs a unique dual suspension system suppressing diaphragm rocking modes. Keep in mind that because it is an active design, a number of compromises have been eliminated from their passive twin. With the implementation of an electronic x-over in the amp module, the passive crossover network components have been removed and thus are no longer subjected to vibrations from the internal back wave of the drivers. The biamplified system is able to power the drivers without the significant power losses of a passive network. Separate active circuits can individually control magnitude and phase allowing both to be optimised, and minimising speaker cabling allows you to control the bass driver by maximising the damping factor. The SCM19A is an important addition to ATC's extensive domestic lineup. The combination of power handling, ruggedness and lack of colouration are qualities that make ATC speakers a leading product.

  7. A Raspberry Pi Music Night 8pm Wednesday 16th January, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month's Melbourne Audio club meeting will be entirely presented to you by your committee members. They will present to the club a selection of music from their favourite CDs. It could be a track from their 'desert island discs' or a recent purchase. To ensure that we get through as many different tracks, I've requested that each track be no more than 5 minutes long. This will get us through plenty of music before the coffee break. While it's good to have a music program of varied tastes, the audio system to play it on, will be just as interesting. Chris M will start off the night with his 'Raspberry Pi' Music Server. This super versatile palm-sized computer was developed in the UK to promote teaching of basic computer science in schools. Now in its third generation, many DIY groups have developed several different uses for this computer, everything from a Home Weather Station to a Media Server for your television. The 'Pi' has its own Wi-Fi output as well as four USB2 connections. Chris operates the unit from a tablet with a modified program called Moode. His music selection will be sourced from a USB drive while his latest DAC, XMOS U8 which uses an AKM chip from their 'Velvet Sound' generation, will take care of the sound. An OPPO multi disc player will also be available on the night for the other members to play their discs. This would be a good opportunity for all members who are new to the club, as well as the regulars, to discover some new sounds. I'm sure the guys on the committee will do their best to present a thoroughly satisfying night of music. Nick Karayanis , Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  8. Rockian Trading and Osborn Loudspeakers 8pm Wednesday 21st November, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 Once again we thank Greg and Yvonne Osborn for their technical and moral support for our annual November MAC meeting. This year Greg intends to use his Epitome Tower Reference speakers driven by AM Audio 833MS power amplifiers controlled by an AM Audio RT-3 Ultima pre-amp with signal from an Audio Aero LaFontaine SACD player and a Consonance Die Walkure turntable with a treasured old Clear Audio cartridge. As usual Beverley will have a selection of recordings for sale through to MAC members at special prices. Some particular bargains will continue to be presented from the Rockian Trading catalogue. With the continuing growth in digital downloads and streaming our sales of digital discs has continued to decline this year. Thankfully, sales of LPs have increased. And I notice the variety of exotic turntables, cartridges and phono-preamps seems to increase every time I visit the relevant web sites. We can buy a Koetsu Blue Lace Onyx Platinum MC Phono Cartridge for $14,995.00 (US$), and there are a growing number of specialist phono preamps. Amongst these preamps are units that digitize and process the analogue signal to removing all the clicks and noise before feeding it to the USB port or outputs to power amplifiers. I have a close friend and music associate who has just purchased a "digital" preamp so he can play his extensive LP collection through his computer system. He does have a fine pair of modified Tannoy Monitors that were once part of a quality stereo system attached to his computer. He hasn't had a dedicated stereo sound system for at least a decade. The Tannoys are set up behind his work desk about two meters from his chair. They are regularly used in conjunction with a very subtle subwoofer under the desk to produce music. Stuart Beatty is a singer/guitarist I have worked with for about forty years. This situation has become particularly relevant to me because I am in the midst of producing a CD of The Delmatics, a rock and roll band I have lead for more than thirty years. We have found a great, small studio owned by a genius digital engineer, Michael Zammit, who is also an accomplished musician. I quickly discovered his skill in manipulating multi-track digital signals to be outstanding. He works in a control room dominated by a pair of Yamaha HS8 (8inch two way) Monitors with an appropriate Yamaha subwoofer. The studio doesn't have a pair of quality full range speakers so I will borrow a pair of Osborn Eclipse speakers to use in the studio to finish the final mix and perhaps produce a master. We reached the point where a 'first' mix was done and CDs burnt for band members to audition and report any changes they required. What interested me was discovering what they used to audition the first mix CDs. Apart from Stuart's near-field Tannoy set-up Stan, our second vocalist and guitarsynth player has a pair of JBL EON 615, PA speakers, d-class powered 15inch 2 way speakers. He also auditioned the CD on his TV with an attached sound-bar. Rob, our vocalist and drummer, only had the CD player in his Hyundai i-load sound system. For my part I have seven different operational stereo systems plus five different sound systems attached to computers in our offices, workshop and studio. I have three working turntables. Never mind! The aim is to produce a recording that sounds exciting on all devices and systems. This production process has reinforced my long held understanding that making music is such a subjective activity, no one is wrong and every opinion counts. At first it seemed to me the mp3 generation had taken over and people like us who are interested in discreet stereo systems had become an outdated minority. Then I witnessed hundreds of people attending the two recent audio shows in Melbourne and I was encouraged to continue promoting and selling quality recordings. The exhibits at these shows varied from quaint, expensive curios to awesome systems producing sonic magic with quality staging, with stereo imaging and depth of field. These are important stereo qualities I have yet to encounter using headphones or near-field monitors. When I was seeking quotes from replication companies to manufacture The Delmatics recording they all asked if we required LPs or CDs. They all report that it is now common for independent music producers to release LPs and include free access to download the digital file with each LP. One of Melbourne's major replicators has recently installed an LP comparator for clients to select their preferred pressing plant. They have set up four identical turntables with identical cartridges playing the same recording, mastered and pressed in four different factories. I have yet to visit this facility in Richmond. I recently experienced some of the magic enthusiasts encountered regularly in pre-CD days. I replaced the Vandenhull modified Adcom high output moving coil cartridge with a Micro Seiki VF-3200e moving magnet cartridge in my Ariston Q-Deck turntable. This turntable is attached to a sixty watt per channel Hafler system driving a pair of Chesky C-1 speakers. The difference is so marked it's like having a completely new collection of records in my racks. Every record has a much more detailed upper midrange and a wider, more defined stereo image. The Micro Seki cartridge has been stored for years in my 'jobs to do box' with a bent stylus cantilever. It was damaged years ago when we moved house from St. Kilda to Balaclava. I finally found a source for an OEM replacement elliptical stylus. $75.00 well spent. I remembered the Micro Seiki being 'a really nice cartridge' but I had forgotten just how 'nice.' This development is important to us because we are auditioning more and more LPs on the Ariston Q-Deck these days. Where possible I will use LPs to demonstrate the 2018 releases. Besides the Original Master Recordings from Mobile Fidelity, Reference Recordings, Opus 3 Records, Stockfisch Records and Chesky Records produce LPs. Rockian Trading continues to market mainstream labels like ATMA Classique and Cala Records through stores like Readings Books and Music stores. We also provide audiophile labels to specialist stores like Quality Records in Malvern, Greville Records in Prahran and Audiophile Reference Recordings in Clayton, as well as to hi-fi stores like Tivoli Hi Fi in Hawthorn, Audiophile in Heidelberg Heights, HiFi Exchange in Clifton Hill and a growing number of other specialist stores all around Australia.

  9. M8Audio 8pm Wednesday 17th October, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 It's not that often that we get someone who has travelled all the way from Queensland to present at club. Mark Thomsen of M8audio will be exhibiting at this month's Melbourne International Hi Fi Show, October 12-14 and has accepted our invitation to present at the club following the show. Thomsen is originally from Denmark and moved to Australia in 2009 with his Australian wife. He's an electronics engineer by profession with a specialty in audio. He had been building speakers for years just for pleasure but in 2015 he decided to take his passion to another level - he founded his own speaker manufacturing business. The 'Sweet Maxwell' is the high-end speaker from M8audio that is based on Mark's ideas and experience. This large stand mount speaker uses a honeycomb braced cabinet using the brand's unique viscoelastic dampers. All the woodwork is done in-house using a state-of-the-art CNC router. The 100% hand finished cabinet is made from cross laminated European birch veneer. The speaker uses a 29mm Beryllium dome tweeter and a 7.5inch Egyptian papyrus cone low frequency driver with a neodymium motor. The electronic equipment that Mark will be using on the night are all new products and brands never before seen or sold in Australia. The DAC212SE by DiDit High-End is made in The Netherlands. The DAC is truly unique in its implementation of a balanced design that is more than just a pair of XLR output connectors. A Music Server from Belgium, the 432 EVO, will be providing all the music for the night. This two box unit can rip your CDs; play all your Hi-Res files up to 32bit PCM and DSD 128 and support HDMI Audio as well as USB. With a 2TB of storage it can hold up to 6000 CDs. Mark will also be introducing the distributor of the electronics, Ian Brown from Critical Sound New Zealand, as they will be sharing a room at the Hi Fi Show. So if you can't get to the show then don't miss out the club meeting. I'll be at both. Nick Karayanis Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  10. CartridgeLab, a Comprehensive Phono Presentation 8pm Wednesday 19th September, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month we are in for a very special and entertaining presentation. Leigh Fischer from Interdyn, who import the full range of Pro-Ject turntables and more recently Ortofon will be conducting a phono cartridge demonstration. "CartridgeLab is an interactive demonstration tool, designed in Australia, which allows us to explore key models in the Ortofon cartridge range." A Pro-Ject 2Xperience SB Turntable is modified by fitting an Ortofon TA-110 Tonearm accompanied with a suite of eight cartridges. The headshell mounted 2M series moving magnet and Quintet series moving coil cartridges are weighted to be swappable, allowing Leigh to quickly move through the models. We will be listening to the cartridges through a system comprising of a Pro-Ject phono stage, a Tube Box DS2 with its switchable front phono settings which allows us to explore some of the characteristics of the phono cartridges. A Rotel Pre & Power Amp combo, the RC-1592 and RB-1590 will supply plenty of power to tease out those transients as we move up the Ortofon range. A pair of PMC Twenty 5.26 floor standing speakers will provide the sound energy to fill the Willis Room. A three way design, this flagship model from the Twenty5 series of speakers, comprises of a 6.5inch bass driver, a 2inch dome midrange and a 27mm tweeter. The Twenty5 represents the latest in a series of evolutionary stages in perfecting the company's ATL (advanced transmission line) interpretation. "This system showcases the increased dynamic response and openness of moving coil cartridges, along with the increased resolution of more extreme stylus profiles. During the demonstration we'll explore key points of differences in cartridge design and discuss the trade-offs, benefits and - perhaps most interesting - the inevitable compromises we can encounter within the analogue world." Sounds like we're in for a very informative evening. Nick Karayanis Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  11. Lucie Audio 8pm Wednesday 18th July, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 When it comes to choosing or designing a loudspeaker there are two rules to consider: Rule #1; There is no such thing as a perfect loudspeaker. Every design is a series of compromises. Rule #2; One has to accept that there will be compromises and decide on a design which reduces these compromises. This month's presenter has developed a speaker system which further reduces the compromises associated with the conventional passive loudspeaker. Rick Bond from Lucie Audio will be demonstrating his speaker system which utilises active crossovers with room equalisation by means of his DSP pre-amplifier. "Our pre-amp is built around the capabilities and feature set of the MiniDSP 2x4HD processor board. This gives us the power to process the stereo audio stream in real time to perform room corrections and digital crossover functions. Correction technology is powered by Dirac Research AB, world leaders in this field". The process maps out the frequency and impulse response characteristics of the speakers in the room in a 3D grid around the listening position. After completing a frequency sweep with a microphone connected to the computer, a desired frequency response curve and an optimised impulse response are measured; the data and a set of filters are generated to map the two together. This data is then uploaded to the unit and stored in one of four configuration slots. This provides great flexibility in that up to four combinations of tonal response, crossover parameters and optimal listening position can be stored and readily recalled via the unit's remote control. "To get the best from the MiniDSP hardware, we developed an active analogue volume control board. Maintaining volume control in the analogue domain provides the best approach to the gain structure". Rick will be demonstrating his system with two sets of book shelf speakers and a matching subwoofer. He has developed these two distinct speakers to cater for the tastes of the listener. The Lucie Model One Loudspeaker is a 6.5" Point Source design. The full range driver is sourced from Dayton Audio for its zero crossover distortion. Excelling at delivering the nuances in the midrange, this design is recommended where primarily acoustic music is appreciated in a small to medium, focused listening environment. The Lucie Model Two Loudspeaker is a traditional two-way compact speaker with drivers from SB Acoustics and Scan-Speak. Recommended and pre-set crossover slopes from the DSP Pre-Amp are set at 6db per octave and centred at a fairly high 4kHz. First-order crossover slopes are chosen for their phase neutrality, made possible by the smooth and extended response of both drivers. This bass reflex (ported) design has a greater power handling and more driver excursion, better suited to bass-heavy music. The system extends the response well below the frequency of the cabinet, giving exceptional performance for a fairly compact enclosure. Cabinet materials are chosen for their high density and sustainability. Narrow grain carbonised Bamboo or Baltic Birch ply are laminated, no veneers are used, precision CNC cut then hand assembled and finished. Due to the laminar sheet construction inner wall profiles are able to be uniquely contoured to minimise internal reflections and cabinet resonances. This will be Rick Bonds first public presentation at an audio event. A relative new-comer to the HiFi scene, this young man has developed a complete active system that puts DSP technology within the reach of many audiophiles.

  12. Convenors Request Night with gear by Ray Goh 8pm Wednesday 16th May, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month's meeting will be a music request night with the club Convenors providing the musical program. Each Convenor will present to the club a selection of music from their favourite CDs. It could be a track from one of their 'desert island discs' or a recent purchase. To ensure that we get through as many different tracks as possible, I've requested that each piece of music be no more than 5 minutes long. This will get us through plenty of CDs before the coffee break. Equipment on the night will be provided by Ray Goh from the Hi Fi Exchange. At the time of this write-up, Ray was still finalising the equipment selection. With so much gear to choose from, his new shop is an Aladdin's cave of classic old gear looking for a new home. Whatever gear he puts together for the night, I'm sure it will be a thoroughly satisfying musical presentation. This would be a good opportunity for all members to discover some new music at this meeting. I'm sure your music Convenors will do their best to present a most enjoyable night.

  13. Redgum Audio the Black Series 8pm Wednesday 18th April, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month we welcome back Ian Robinson and Lindy Gerber from Redgum Audio. The last time we had them present at the club, they had just celebrated an audio milestone - 21 years in the Hi Fi Industry. Since then a number of new components has been developed, thus the product theme for the night: All things black and (mostly) small. The Redgum Black Series of components will comprise of the RGMP8 Media Player - $990, the RGDAC8 DAC - $990 and the RGi35ENR amplifier - $2000. All designed in Melbourne and assembled in China. To complete the system a pair of Axis VoiceBox S Mini-Monitors - $2500 - in a glossy black finish. The Media Player and DAC are designed to be hidden or stacked together on a hi-fi rack; they share the same size chassis and footprint. The RGMP8 Media Player is perfect for those who just want to play their files. This stand-alone media player automatically creates its own wi-fi hotspot, no internet connection or network required. It is designed to be used by someone who has little computer knowledge. Long before the term "Asynchronous" became widely used, Redgum CD players and DACs have been asynchronous from the first model. The RGDAC8 has been ear-tuned to be at least the match of the sonic quality of their top-line DAC. This 3rd generation model has become a Multi-format Hi-res Asynchronous USB DAC. The Black Series RGi35ENR is the 65wpc Integrated amplifier, purpose designed to power ultra-low speaker impedances, 95 WRMS into 2ohms with short term transients of 560watts. The Axis VoiceBox S Mini-Monitor with its 50mm Metal Ribbon tweeter has the sonic virtues to bring out the quality of the electronic components. This system has been presented in the U.S. at the Newport Show and AXPONA, receiving an Audio Oasis Award. Sounds like we will get to hear an all Australian quality system that won't put you in the black.

  14. Melody Valve Ltd 8pm Wednesday 21st March, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 2016 was a landmark year for Melbourne audiophiles, for it was a year when two International Hi Fi Shows came to town. Not only was it a first time for the StereoNet group to organise a very successful show, it was a first for Melody Valve Ltd to exhibit all of their new amplifiers. This month we are very lucky to have Melody present at the club. Established in Melbourne by the founder and chief designer Mr Allen Wang, the company has grown by investing in their own factory in Shenzhen China. It features a modern assembly line, a transformer production line, a vacuum processing plant and a variety of self-built high-end testing equipment. Their current line of amplifiers consists of eight models. Melody will be demonstrating two systems from their Everest amplifier range. The equipment will consist of a 28watt Class A Integrated amplifier, and a Pre/ Power combination. The first model the "Everest 845", uses a Western Electric 845 tube per channel, as well as a pair of 300B driver tubes. The second system will be a pair of mono blocks - "PM 845 EVO" -- each running a pair of 845 valves in Class A mode with a combined output of 70 watts each. The "WE2688 Signature Pre", is a real highlight with its implementation of a WE 416 tube; planar triode, used for microwave telephone systems, that looks like a round metal relay. The two systems will use the same pair of speakers, the Harbeth 40.2. This reference monitor is a 3-way stand mount model that houses a 12" Bass driver with 6.5" Mid and matching 1" Tweeter. Harpeth's top of the range speaker is modified for the domestic audio market with a different bass driver, but still retains the same mid that is used in their studio monitors. If you haven't experienced Melody's presentations at the past Hi Fi Shows, you will see why they get the award for "Exhibitor who tried the hardest to impress". Sounds like we're in for a sonic spectacular. Nick Karayanis Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  15. QEOS II by Perfect 8 Technologies 8pm Wednesday 17th January, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 When it comes to cabinet construction, many speaker designers will traditionally use some type of wood to produce a finished product. In the past, unconventional material like concrete has been tried. Today, everything from 'high-density polyurethane' to aluminium is in use. Glass would be the most unique and challenging material for any speaker designer. In 2016 the Australian Hi-Fi & AV Show hosted the world premiere of the QEOS II. These new glass speakers are designed in Sweden, produced in Germany by the renowned glass furniture manufacturer Dreieck Design, while the crossover filters are made in Australia by Spuncsound founder Roland Boitor. This new model is inspired by Perfect 8 Technologies earlier 'Cube' speaker but with increased inner volume that delivers enriched sound. This team of specialists believe glass has become the ideal structural material for a new revolutionary high-end audio solution. One key technology used in the QEOS II speaker, is the proprietary Super Silent Glass (SSG) "SSG is a special glass type which virtually eliminates all vibrations there is no ringing." The new stand mount speaker is fabricated from 12mm thick glass panels. The sealed glass enclosure houses two 7-inch aluminium drivers and a 35mm fabric dome tweeter. The mid/bass drivers are mounted on opposite sides of the cabinet, thereby delivering a virtually omni directional radiation pattern throughout the heart of the music, up to 900Hz. The tweeter which faces the listener delivers its sonic signature from 700Hz (!) and looks after the high frequencies. Roland Boitor from Spuncsound, will be presenting a program of music to demonstrate the sonic attributes of these speakers, as well as their technical highlights. Loudspeakers are often described as being a window on the performance; with this new revolutionary material, we get to see and hear the results.

  16. DIY Night 8pm Wednesday 13th December, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 It's that time of year again when the DIY group get to show off their Hi Fi projects at the December General Meeting. It looks like another busy year for the group as they have managed to put together three systems for the night's presentation. This year we are lucky to have a wide range of equipment on show, everything from vinyl to a music server, and both Class-D and Valve amplification. The Audio Action group will be demonstrating their finished project, a Phono Preamp designed and built by a team of MAC members. The first system will be playing music from a DIY "Raspberry Pi" music server. Based on a low cost but very powerful computer board aimed at the educational department. This same system will feature a 250W Class D amplifier powering a pair of 2-way stand mount speakers. The second system will showcase the MAC Phono Preamp, designed with two 'best in class' head-stage amplifiers, one for MC and one for MM cartridges. The rest of the system will have an opamp based preamp running into another Class-D power amp. A pair of 3-way speakers with American 12" bass drivers, Scandinavian 5"mid's and 'Raal' ribbon tweeters, will be providing the sound for the night. The final system will feature a valve amplifier with a modest 15 Watts. The design is a hybrid of Dynaudio ST70 and Alan Wright's ideas using EL34's in ultra-linear mode. The amp will be partnered with equipment from the other two systems. As in previous years, each system will be allotted 30 minutes. Each presenter will get to explain their gear as well as play some music. This should see us finish the session by 10:00pm, allowing the members on the night to hear all the systems. Its going to be a cracker of a night. Nick Karayanis Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  17. Rockian Trading and Osborn Speakers 8pm Wednesday 15th November, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 Once again the month of November has arrived and our regular presenters for this month, Ian and Beverly from Rockian Trading, and Greg from Osborn Speakers will be introducing their products. Stocking a selection of high quality vinyl records and CDs from Mobile Fidelity, Chesky, and Stockfisch Records, Bev will have her bazaar set up for eager MAC members to purchase some bargains. This is always one of the most entertaining evenings for the year, with lots of anecdotes from Ian and his playing examples of new discs. I am told that a lot more of the black vinyl will be featured on the night. After last month's presentation with the new Mobile Fidelity turntable, it looks like we are in for some grooving sounds. Who would have thought that records would be cool again? Note: Beverly will have her bazaar set-up to go by 7:00 pm. Nick Karayanis Program Co-ordinator Once again we thank Greg and Yvonne Osborn for their technical and moral support for our annual November MAC meeting. This year Greg intends to use a 100 watt per channel Consonance system driving a pair of Osborn Reference Epitome loudspeakers. As usual Beverley will have a selection of recordings for sale through to MAC members at special prices. Some particular bargains will continue to be presented from labels that have left Rockian Trading or ceased regular production. In 2016 I reported on the decline of CD sales and the proliferation of on-line streaming. The transition from "the real world" to "the virtual world" continues. Music recordings are now "sound files" and the programs that control them are "apps." Telephones, computers, tablets and walkmans are now devices, and devices are all pervasive. Artists, from world fame like Madonna to local heroes like Mike Brady are regularly struggling with audience members who persist in waving iPads above their heads to video the performances. Never mind the view of those sitting behind them. Like the modest mobile telephone transformed into an incredible "Swiss Army Knife" of portable gadgets, technology has also transformed the humble gramophone into dedicated audio devices that reproduces the best possible sound. Or has it? Something happened. I recently re-commissioned my 35 year old Celestion 18" 3 way P.A. system, powered by two Hafler Pro500 amplifiers. Looking for a dramatic, dynamic recording to check the system I selected one of my FIM 'Producers Choice' CDs and put it into my trusty old Denon DCD 815 CD player and pressed play. It sounded horrible. The 1" metal dome RCF compression tweeters made the strings sound gritty, like sand-paper dragged across the back of a panel saw. I was horrified and feared the system a failure. Then I changed tracks to one produced by Keith Johnson at Reference Recordings. Glorious huge, clean, dynamic sound. Finally I played a GRP Live In Session CD and Dave Grusin, Lee Ritnour, Carlos Vega and friends performed live in my basement. Remember this is very big Class A-B public address system designed specifically to reproduce live bands, and it performs very well to purpose. The question was, why did the first track sound so bad compared with what followed? It had to be the CD player. In its day the Denon DCD 815 CD player was a decent mid-priced unit. The DAC is good but the error correction is primitive compared to modern devices. Quality modern players extract raw digital information from the disc and reconstruct it before the output in a signal computed to be the best possible sound. When your player makes a humble off the shelf CD sound so good, who needs an expensive audiophile quality CD or SACD. Our sales suggest only a few people now require audiophile digital discs. On the other hand, more and more people are returning to analogue. LP sales continue to firm. No digital trickery here, just good production standards of "real music." Now all I have to do is compare the mono mix with the stereo mix. Hmmm! Besides the Original Master Recordings from Mobile Fidelity, also Reference Recordings, Opus 3 Records, Stockfisch Records and Chesky Records, are producing LPs. Rockian Trading also continues to market mainstream labels like ATMA Classique and Cala Records through stores like Thomas Records and the Readings Books and Music stores. We also provide audiophile labels to specialist stores like Quality Records in Malvern, Greville Records in Prahran and Burwood Music Centre, as well as to hi-fi stores like Tivoli HiFi in Hawthorn, HiFi Exchange in Nunawading and Vinyl Revival in Fitzroy.

  18. Avantgarde Acoustic Zero TA XD 8pm Wednesday 19th July, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month we welcome to the club a local importer of High End audio equipment Cameron Keating from Maxmedia, who will be presenting a selection of European Hi-Fi brands, one of which Avantgarde Acoustic from Germany, would be a very familiar name with horn speaker enthusiasts. Cameron will be demonstrating the newest model in the Avantgarde range, the Zero TA XD. This entry-level speaker encompasses Avantgarde's 25 years of know how in hybrid horn loudspeakers. Up until now, Avantgarde fans have had to choose between one of the company's bigger, more expensive hybrid horns. Standing just over a meter tall, this new three way model is described as a semiactive horn system. The objective was to accomplish the clarity and power of its 'bigger' brothers, in a significantly reduced enclosure. Employing Avantgarde's CDC technology, the midrange driver has no passive filter components in the signal path. This results in a sound characterized with an effortless clarity and explosive vitality. The 400 mm spherical midrange horn crosses over at 300hz to a DSP-controlled 10-band parametric subwoofer. This 12 inch long throw driver is powered by a 500Watt amplifier. Partnering the speakers for the night, will be the LAB 12 Mighty Power Amplifier. This single ended class A valve amp, will be driving the mids and tweeters with only 10 Watts. Matched to its pre-amp, the LAB 12 TRUE is a Passive Attenuator / Input Selector. The LAB 12 DAC 1 will be taking care of the digital to analogue duties, with classic non oversampling (Phillips TDA 1543) and a tube based output stage. Not forgetting a second DAC from iFi the Micro iDSD BL will be taking a turn. The font end source will be a music sever from INNUOS, the Zeneth Mk II. With a system sensitivity of 104 dB, the ZERO TA is 32 times the dynamic range of a conventional 87 dB box speaker. I think we're in for some fireworks for the night. Nick Karayanis Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  19. The Camel Audio Action Project 8pm Wednesday 21st June, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 Once again the Annual General Meeting has come around for another year. It is always the intention to keep business dealings at the meeting to a minimum, with nominations for Committee positions and Music Convenors. After the club business, we will be entertained for the night by the guys from the Audio Action group. No, this isn't a cabaret act, but a group of MAC members who have been lead by Ron Newbound in developing a speaker project. Over the past twelve months, the group has been collaborating in designing and building a 'Camel', well that's what Ron calls it. The 'Camel' in question is actually a three way Transmission Line speaker, but not in the usual tall rectangular box shape. Well what do you expect when you get a dozen MAC members together to design a speaker? This unique looking speaker is based around a cylindrical enclosure that houses the transmission line, while the front baffle presents to the listener a 'surfboard shape' that seems to float off the floor. You could even say the selection of drivers is unconventional. The tweeter is an air motion transformer (AMT), while the mid and bass cones are made from aluminium. Ron will start the presentation with a short explanation on some of the technical issues with building such a speaker. How some of the challenges were resolved as well as why the group chose to develop this type of speaker. Then each member from the group will get to play a piece of music to the club. Ron assures me that the group will have a good selection of music that will demonstrate the best performance out of the speakers. Sounds like we will have an interesting and enjoyable night. Not to be missed. Nick Karayanis Program Co-ordinator Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
  20. B&W 600 super speakers, Classe 600w, NAD Master M32 8pm Wednesday 15th February, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 Bowers & Wilkins B&W 800 D3 and B&W 805 D3 Convoy International is the Australian importer for what arguably is Britain's most famous loudspeaker company: Bowers and Wilkins. For half a century B&W has been building speakers, and their latest 800 series represents a landmark in the company's history. Specifically created to celebrate B&W's 50th anniversary, the 800 series has been re-invented, from the cabinets through to the drive units, just about every component has been newly developed. Two models will be demonstrated on the night, the 800 D3 and the 805 D3 and in two different systems. The B&W 805 D3 will be first. This stand mounted speaker uses a 165mm bass/mid driver matched to B&W's famous Diamond Tweeter, quite a step up in materials from cloth or base metals that are usually used to build tweeters. Powering these speakers will be NAD's newest flagship integrated amplifier, the M32 from their 'Masters' series of hi-fi components. Speaking of flagships, the second system will feature B&W's most distinctive looking model, the 800 D3. This three way floorstander with its Nautilus tube, in which the tweeter is mounted, the 'head' containing the midrange driver, and the bass unit, are all entirely new. Gone is the yellow coloured Kevlar material now upgraded to a metallised finish on the midrange cone. Just as striking is the new head, reshaped to enhance its rigidity, it now sits on the shoulders of the bass cabinet. The most obvious change is the curved front to the bass cabinet, into which are fixed circular metal mounts for the two 12-inch bass drivers. To prevent cabinet vibrations and inhibit standing waves, a system B&W calls 'Matrix' bracing has been optimised, while the back of the cabinet gets a finned alloy heat-sink, it's not just there for looks. The B&W 800 D3 deserves a flagship system to show off their abilities. From the stables of Convoy, a pair of CLASSE mono blocks will power the speakers. The CA-M600 amplifiers put out 600 watts each, plenty of headroom for the speakers and the size of our room. The matching CLASSE CP-800 II Preamplifier/Processor will complete the system. With such a distinguished brand of high-end speaker and amplification at the MAC, the best seats in the house are going to fill up very quickly.

  21. Joe Rasmussen, Custom Analogue Audio, JLTi 8pm Wednesday 17th May, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 This month the club is very privileged to have an audio enthusiast travel all the way from Sydney to present at the club. Joe Rasmussen is known among the DIY audio fraternity as the "Father of the Buffered Gainclone" His collaboration with the late Allen Wright, led him to develop several projects starting back in 1975 with a "hybrid tube amplifier" In 2001 their work saw them develop upgrade modules for the first generation Sony SACD players. Joe will be presenting at the club his latest upgrade projects. The JLTi Oppo level 4.2+ACB, is a highly modified Oppo-105D fitted with no less than eight modules. Each having a specific task - Master Clock - DAC Clock - Terra Firma power supply - all designed and developed by Joe at Custom Analogue Audio. "Ultimate Digital playback deserves Ultimate Stability! This is about the importance of clocking CD players and digital playback, a new standard of performance. How to make digital sound more like good vinyl". His collection of equipment that will fill the room with sound, will include two amplifiers, a prototype "Beyond Triode" amplifier - A New Type of Tube Amplifier, and a DIY 40 Watt "Transconductance Amplifier" This solid state unit will be brought along for a bit of fun. Designed to output 'current' it will be demonstrated with his Elsinore Mk6 speakers. Compatible with this amplifier they can be driven from any source impedance and hence does not rely on the 'damping factor' of the amplifier. The "Beyond Triode" amplifier encompasses thirty years of experience and developments rolled into one design. The prototype unit a Yaqin MC-100B, has been upgraded to give a great boost in the 'Permeability' of the output transformers, which then translates into an extreme level of resolution. To round off the equipment list for the night, two versions of the JLTi Phono Stage will be presented, a single box unit, and the new Deluxe Phono Stage. The Deluxe version is a two-box unit with a 'beefed up' design in the gain and buffer stages plus a massive separate power supply with extreme filtering that reduces power supply noise. What Joe Rasmussen has achieved by taking a good quality product, amp or CD player, and lifting its performance to more than just one level, but several, makes music sound just lovely - Just Listen To it.

  22. A Night with Hugh Dean, Aspen Amplifier Designer 8pm Wednesday 15th March, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 The name Hugh Dean is synonymous with the Aspen amplifier range. His kit form amplifiers have won many hearts among audio enthusiasts who appreciate a very high standard of sound. The Maya 200 and the SAKSA 85 amplifiers are a culmination of over twenty years innovative design, starting in 1974 with the Glass Harmony. The Maya was conceived in 2015 with a topology breakthrough, which Hugh will attest has brought huge improvements in speed, bandwidth and clarity. This 200W per channel amplifier comprises four discrete stages: Input stage including a feedback node, Voltage Amp stage, Driver stage, and the Output stage which uses a pair of very large 480 watt MOSFETS. Hugh's primary aim in his amplifier design is very low odd order harmonics. The MAYA avoids phase issues with extremely linear first and second stages. With very low THD, less than 0.025% into 200W and very low noise, the Aspen amplifiers have none of that solid state glare. The amplifiers can be bought as a DIY build from a pair of tested and assembled PCB modules, starting at $930 plus GST for the SAKSA 85, and $2200 plus GST for the MAYA 200. Both units can now also be purchased with purpose built full enclosures. An OPPO 105 multi-disc player will be playing the music, while a pair of classic KEF 105/3s will entertain us with their sound. The 105/3 was the first Reference Series Loudspeaker from KEF to incorporate Uni-Q technology. This four way floor-standing speaker embodies several advanced and unconventional design features for its time. Its bass section drivers are mounted within the cabinet in a double coupled-cavity configuration. The combined output of the two woofers is radiated through a front mounted 6" inch diameter port. The D'Appolito array on the front panel is shared with a pair of midrange drivers and a KEF Uni-Q driver, with a concentric 6-1/2" inch cone and a 1" inch tweeter. Midrange bloom, solid state glare, lifeless sound? None of that with Aspen Amplifiers.

Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 Back in October 2013, the club was very privileged to have one of the most influential audio engineers of the analogue world present at the Melbourne Audio Club. He is Mark Dohmann and since then Mark has formed Audio Union. Another first at the MAC, will be a new addition to the Thrax portfolio of equipment. The LYRA loudspeaker will make their debut at the club partnered with a pair of HEROS 100W class A mono blocks and the matching DIONYSOS pre-amp. The Lyra is a two-way, three driver monitor sporting a vented enclosure that is made of aluminium plates, screwed together. The D'Appolito array on the front panel, incorporate two 6.5" woofers with magnesium membranes and copper phase plugs. The tweeter is a ring diaphragm compression driver crossed over at 1.5 kHz. Its shape was developed by Spherovox with specific directivity and frequency response.

  24. Annual MAC DIY on show 8pm Wednesday 14th December, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 It's that time of year again when the DIY group get to show off their Hi Fi projects at the December General Meeting. It looks like another busy year for the group as they have managed to put together three systems for the night. Our first presenter will be doing a short Master Class, his topic: Repairing Quad ESL63s. The talk will basically be about the pitfalls involved in repairing ESL63s, as well as a practical demonstration with some faulty panels, then finishing off with a music presentation with a pair of DIY Q405 amplifiers. The other two systems will be showcasing the opposite ends of amplifier design. One will be a classic valve amplifier that uses KT150 tubes with a 60w/channel output, the other, a solid state Class D design that puts out 75W into 8ohms. Both have been designed from the ground up, with a no compromise approach when it came to parts and circuit design. The program for the night will run the same as last year. All three systems will be demonstrated before the coffee break. With each system having an allotted time of no more than 30 minutes. Each presenter will get to explain their gear and play some music. This should see us finish the program well before 10:00pm, allowing all the members on the night to hear the three systems. The earlier ending to the night's program will give us a chance to ask the talented DIY presenters about their projects. We all know how passionate our members can be when it comes to building their own equipment. See you on the night.

  25. Rockian Trading: Hoopers + Osborn 8pm Wednesday 16th November, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 As on more than twenty previous occasions, we thank Greg and Yvonne Osborn for supplying a pair of their outstanding speakers, appropriate amplifiers and a player to demonstrate some of the last year's releases. As usual Beverley will have a selection of recordings for sale through "Bev's Bazaar" to MAC members at special prices. Some particular bargains will be presented from labels that have left Rockian Trading or ceased regular production. Last year we reported the death of two audiophile pioneers. This year, because so many associates are reporting the decline of CD sales, they are also predicting the demise of the digital disc medium. Observing that most of the exhibitors at the recent Hi-Fi & AV Shows used laptops and tablets to control and supply signal to their equipment strengthens and confirms this trend. One colleague remarked, "All of this digital technology is doing my head in!" Thankfully there are still some music collectors who want to own an "actual" recording, rather than the virtual version. So LPs, CDs, SACDs and Blu-Ray Discs still find sales. In fact, demand for LP records has grown to the point where most of the major labels, and a few of the minor labels, are pressing "records" again. Unfortunately a number of these "new pressings" are of less than ideal quality and records are regaining the reputation of being "noisy." This can often be true of albums purchased at bargain prices from discount stores and suppliers. Even the 200gram pressing is no guarantee of audiophile quality. Besides the Original Master Recordings from Mobile Fidelity, Reference Recordings, Opus 3 Records and Stockfisch Records are producing LPs. An occasional title from Linn Records, and some recent releases from Chesky Records have also appeared on LP. Rockian Trading also continues to market mainstream labels like ATMA Classique, Cala Records and Linn Records through stores like Thomas Records, and the Readings Books and Music stores. We also provide audiophile labels to specialist stores like Quality Records in Malvern, Greville Records in Prahran and Burwood Music Centre, as well as to hifi stores like Tivoli Hi-Fi in Hawthorn, Hi-Fi Exchange in Nunawading and Vinyl Revival in Fitzroy. Since LPs are now our most popular medium, and we talked about LP releases at the November meeting last year, we feel obliged to present some LPs to the club this year. We are trying to obtain a MoFi UltaPlatter turntable, released at the the High End Munich audio show in May, to demonstrate some of the better vinyl releases. Regardless, we will be demonstrating some LPs this year. Ian Hooper - Rockian Trading. Ken Tripp Wise and Wonderful Webmaster Melbourne Audio Club, Inc. http://www.melbourneaudioclub.org.au
