  1. Item: Audiophilleo2 Location: Williamstown VIC Price: $320 Item Condition: VG Reason for selling: NLR Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: This will turn any reasonably priced dac Into a world class digital source. I’ve had this usb/spif converter for many years and it never fails to improve and impress. While most DACs now support USB, chances are most will sound way better when driven by an Audiophilleo. Every Audiophilleo USB device is highly-optimized for delivering all those bits via S/PDIF with the most accurate timing possible. Your DAC will simply love it! The “secret sauce” inside every Audiophilleo is a unique combination of ultra-low-noise clocks, advanced signal processing firmware and special EMI-reducing techniques. It’s an elaborate solution—way beyond what most DACs include—but it’s the only way to make all those “jitter bugs” head for the hills. Very competitive priced for a quick sale.

  2. For those interested in over-achieving USB to Spdif converters, this review is for you. I actually wrote this review about two years ago, however I still feel its as relevant today as it was then. The post was originally hosted on my 2channelaudio.blogspot.com.au site. This blog is no more.... I have since moved my 'entire' blog to grizzlyaudio.blogspot.com.au ... The review can now be found at the following address: http://grizzlyaudio.blogspot.com.au/2015/08/yellowtec-puc2-lite-comparisons-made-to.html I have extracted the review and posted below... I hopes this helps HiFi lovers looking for an awesome usb device! ------- Yellowtec PUC2 Lite, Comparisons made to Audiophilleo AP1 INTRODUCTION Let me state this first..... I am in no way affiliated with Yellowtec! I hadn't heard of the 'Yellowtec' brand until I tried this converter. I simply enjoy HiFi and if a product is good I like to share my experience openly and honestly. In general I have no real emotional bond with what HiFi product I purchase, if I hear a better product I generally try to sell what I have and upgrade, 'if possible'. Forever on the quest for better music playback. Prior to 'hearing this converter' I was a dedicated supporter for the Audiophilleo 1, a fantastic USB to SPDIF converter... For some months I listened to music this way. This was until I heard the PUC2 from Yellowtec. I instantly wanted one! and so the story goes. Yes we have the same "audiophile" condition !! So as objectively minded as one can be, I have written the review you see below. I hope this blog post informs and entertains, and above all else helps other DIYers and music/HiFi lovers in their quest for better playback..... especially if the Audiophilleo 1 is on your short list. Lastly, I would like to point out this blog post is not for the purpose of post purchase behaviour reinforcement. As I could have easily kept either converter or both. I selected the 'subjectively' better one, which also happens to be older and cheaper unit, go figure....I will let you decide for yourself. REVIEW TIME..... SOME BACKGROUND PLEASE Here we have the Yellowtec PUC2 lite USB to AES converter. A USB to AES converter which is squarely aimed at the semi/pro recording market. The unit is capable of processing a 192k @ 24bit signal with a dynamic range capability of 105db. The PUC2 lite is a slightly scaled down version of the larger Yellowtec PUC2 USB to AES-3 converter, which has additional line in XLR inputs. For me and most USB to SPDIF shoppers these inputs will not be required, but they do have an up side for those with large vinyl collections, including real-time vinyl capture, or any analog inline in feed for that matter. Yellowtec is a German based, pro audio product engineering/manufacturing business. Its not what you would call a HiFi brand aimed at nonsensical and passionate audiophiles. The business is primarily focused on creating audio technology which is both simple to use and sounds great... work horse equipment for the recording industry. The type of gear used to record the music you listen too.. Now when it comes to HiFi, I am the first to admit the adoption of the latest "tech" does not always deliver "better music reproduction"..... In fact it can invariably lead you off the beaten path quite easily. For example, in an age where 32bit DAC chips are the norm, I still "choose" to use a DAC running a 16bit Phillips non over-sampling TDA 1541a DAC chip, made in the 80's!! Why? because it is highly musical, easy to live with and sounds better than any DAC I have heard in my system. Those who run TDA DAC's in modern circuit designs will appreciate this.... Why have I used this prologue? Well the Yellowtec PUC2 lite is definitely not the most recent converter. From what I can tell, my research suggests the Yellowtec PUC2 has been on the market since 2009, so we have had circa 4 years in modern circuit developments since this unit was released. Concerned? Well you shouldn't be, because this is a fact that in reality has no impact on how the unit sounds, and trust me when I say this unit is of "audiophile" quality and can mix it with top tier converters. So lets take a quick look at what the Yellowtec PUC2 lite offers on paper.... Driver-less OSX and Windows compatibility Option ASIO high performance windows based driver Low Latency performance 192k @ 24bit capability USB Powered / Plug and Play Operation For many a HiFi/Music lover shopping for a USB to SPDIF converter these specs are not invariably different from 100's of offerings on the market. But the PUC2 lite distinguishes itself from the pack, by the way it sounds or should I say doesn't colour the sound (more on that in a bit)... HOW DO I CONNECT THIS THING? What may initially concern some potential buyers of the Yellowtec PUC2 is the "pro" style connections employed by Yellowtec, raising obvious connection questions among consumers, like "how do I connect an AES-3 output device to my DAC which uses a RCA or BNC consumer SPDIF connection?"...... Well don't fear..... You can connect!! and its an easy cable mod for the DIYers.....but lets first finish our connection discussion. In my system I use my custom copper or silver core USB cable with a linear 5v power feed, this takes care of the data signal in from the PC to the Yellowtec PUC2 and 5vdv to power the unit. (Since I wrote this review I have actually partnered the PUC2 full-time with a DIY copper USB lead, which I have found is more synergistic than the silver version in my system. Linear 5vdc power is still supplied via the Teradak PS) The only remaining connection requirement is to get the AES-3 output into your SPDIF DAC. AES3 and SPDIF are well, more similar than not! In a nut shell AES is a professional balanced version of consumer SPDIF. AES operates at an impedance of 110ohm and SPDIF yes you guessed it a trusted 75ohm's. AES operates at a higher voltage than SPDIF, so plugging AES devices into SPDIF inputs requires some care. You can read more on the wiki link... In order to correctly convert AES to SPDIF you are "advised by those in the know" to use a digital format converter. But I am a big believer less in the chain is more, and its rare to have digital sub code incompatibilities between AES and SPDIF devices - so a direct passive conversion 9 times out of 10should be fine, provided your SPDIF receiver chip can handle higher voltage swings... .... AES3 voltage output ranges from 2 to 7 volts peak to peak. Caution is obviously advised here. Additionally, if your DIY AES to SPDIF cable is under circa 2 meters you should experience no issues using this simple DIY cable design. Alternatively, if you would prefer purchasing an off the shelf style cable/adapter, Neutrik sell some nice passive units which impedance match between the 110ohm AES to 75ohm SPDIF.. these units cost around $90 each AUD..... But for the trusty DIY'er, a custom AES > SPDIF cable is pretty simple to make, especially if impedance matching is not employed... My recommendation is to try connecting the unit both ways - Use what sounds better to your ears.... I know I did. MAKING A DIY AES to SPDIF ADAPTER I simply made my AES to SPDIF cable by cutting and terminating an XLR connector to the end of a premade RCA to RCA terminated to an existing 75ohm SPDIF flyead. Pin 2 being Hot Pin 1 being Ground/Cold STEP 1. Parts you will need 1 x XLR female 3 pin plug 1 x Either male RCA or BNC connection to enable connection to your choice of DAC. In my case I require a female BNC plug 1 x Spdif cable STEP 2. The DIY cable Process I simply used a 75ohm high quality SPDIF cable. I cut on end off and terminated a female XLR onto the end. Cable termination is as follows... Termination XLR PIN 2 is Hot, PIN 1 is COLD/SHIELD... Termination RCA/BNC PIN 2 XLR > RCA TIP/BNC TIP PIN 1 XLR > RCA SLEEVE/BNC GROUND Yes right...... the hard parts over..... Moving on. CONVERTER CONNECTIVITY Physically the PUC2 is quite large, measuring 180mm long x 126mm wide x 41mm tall. Its enclosure is simple and military in styling, its purposeful and not made to look pretty. Its a work horse, the Audiophilleo 1 easily wins out in the looks department if not on size alone. The PUC2 enclosure simply does what it should, enclose and protect the internal circuits. Saying this however I personally feel build quality is excellent, so I have no real complaints. What is nice is there's a level of reassurance, demonstrated by the units HiFi prowess that your hard earned money has been spent on components and engineering, not on fluffy little LCD screens, SPL level meters, pretty powder coated/silk screened boxes which add little to the sound of a unit. Personally I think its a nice change to refocus on sound & performance. The PUC2 Lite sports an AES input and output via two XLR connections, a single USB input and a monitor output via a 3.5mm connection which would primarily be used for recording and pro applications. For connection duties, the PUC2 accessories include a dual headed USB power lead, as the unit itself requires more current than one USB port can provide, my guess is circa 600-1000ma however I didn't have the testing equipment to measure power draw, and specifications on power draw don't seem to be available. At the very least current requirements exceed a standard 500ma USB port. This presented no problems in my setup as I powered the PUC2 via a linear 5vdc power supply capable of supplying up to 2amps @ 5vdc. Additional accessories included with the PUC2 include a driver disc/CD with Polytec ASIO drivers for Windows and a discrete OSX driver. A side note on sampling rates: For rates above 48k the PUC2 requires a driver loaded for either Mac or Windows. Yellowtec don't provide a driver for Linux, so this could be an issue for potential Linux users wishing to adopt the PUC2. During my testing the PUC2 displayed rendering issues in Vortexbox with direct hw routing selected. Clipping on bass and treble transients. Plughw works fine but resamples all output to 48k. One interesting item on the accessory CD is the firmware upgrade software. Yellowtec periodically provide free downloadable firmware upgrades to keep your unit current and trouble free. A nice touch! LETS START WITH A SYNOPSIS Let me start by saying and there's no surprises here, yes I like the Yellowtec PUC2 and for good reason. Why? Well its a relatively unknown converter 'the under dog' in a world of hyped and marketed USB to SPDIF converters which is a delight to listen to. When I started my DIY HiFi journey I quickly found you don't always get what you pay for. In most cases you are paying for brand and audiophile royalties These days I like to try products and judge them on their merit, I.e 'How they sound' shock horror!! not by marketing hype and/or spec sheets, or by how much they cost as cost is rarely a good indicator To lead with my synopsis first the PUC2 is highly musical and an extremely transparent performer. When directly compared to the Audiophilleo 1, the PUC2 is a noticeable step up in clarity, transparency, imaging and soundstage. The midrange is noticeably more revealing. Yes Really! The PUC2 paints only the truth, it hides nothing, which makes sense coming from a professional audio house. You hear everything in the mix, the great and well the not so great... At times I found the PUC2 more forward than I would like on poorer /favourite recordings. But higher degrees of transparency & truthful presentation always come at some cost. In saying this I still found the PUC2 highly musical on well recorded tracks, with an innate ability to present a magical soundstage with brilliant colour, depth and insight. The midrange is jaw dropping impressive offering superior levels of transparency & detail over and above the Audiophilleo1, to be honest the PUC2 is scaringly revealing. Choose your poison?! Its all subjective at the end of the day. One must consider that the Audiophileo AP1 is a very well respected converter costing circa $949 + shipping, so this places the PUC2 in very decent company. In fact I believe the Yellowtec PUC2 may even hold its on against substantially more expensive units such as the off ramp from Empirical Audio. Which I hope to try personally in my system soon! To provide a teaser the word from some of my HiFi/Music loving friends is the PUC2 is on par with fully loaded Empirical Audio 4 converter... But I can neither prove or disprove this comment at this time, although I am sure this statement will spark some aggressive posts/lash-back. Remember this unit can be purchased for circa $550 to $600... SO HOW DOES IT SOUND?! MIDRANGE FREQUENCY REPRODUCTION QUALITY The first sound characteristic that struct me immediately when I turned on the PUC2 was the midrange frequency reproduction quality. It is seriously good, outstanding even. It is slightly more forward than some converters (the Audiophilleo / Vlink would be two of these), but the sound mostly remains amazingly detailed, lush and well balanced. Vocal reproduction is flawless, and the PUC2 is equally at home with male or female presentations. Somehow the PUC2 has the ability to strip vocals and instrumentation bare & clean, providing an honest, insightful and musical presentation. I found the midrange reproduction always detailed and transparent and above all else highly insightful. "The PUC2 is like connecting up a pair of high end studio monitors to your system, providing wort's & all honesty." Listening to Jeff Buckley Grace, track 'Mojo Pin' Jeff's breathing & throat movements/swallows between vocal notes are haunting and clearly portrayed, his vocals are presented with beautiful tone and realism, while the soft picks of his guitar and a deep bass drum kick provide a beautiful balance to the track. Cymbal work is beautifully delicate and never harsh. Really nice. The vocal mid range is engaging, forward and musical. On 'Lilac wine' vocals are amazing. Jeff's s's and vocal notes carry a beautiful reverb tail, the PUC 2 places the vocals way out in front of the speakers, and his electric guitar is portrayed with solid thick reverb. The PUC2 really opens up the mix, and lays every instrument and vocal clearly in front of you. Studio monitor'ish' in its ability, the PUC2 has one of the best midrange reproductions I have personally heard from a converter....this is very decent kit. On George Bensons 'Songs & Stories' George's vocals are silky smooth. Midrange guitar frequencies and cymbal/snare work are detailed and penetrating through the mix. The PUC2 portrays a very detail soundscape without any harsh artifacts or glaring. On Diana Krall 'Best Of 2007' track East of the Sun (and west of the moon)" snare work is again beautiful, delicate and detailed. The piano solo, leaves goose bumps on my arms. The PUC2 sounds amazing on piano. beautiful natural tone pose and pace. Diana Kralls vocals at times can become a little harsh, but the PUC2 only produced smooth tones, via my TDA DAC. On the track 'S' Wonderful, Cymbal and shakers add beautiful soundstage, really I don't think I have heard this track sound better in my system. The PUC2 has a commanding capability to render an amazing and detailed soundstage without any overbearing harshness or glare.It successfully walks an innate & delicate line between detail, insight and musicality. I use Rufus Wainwrights track "Cigarettes and chocolate milk" for a decent mid range male vocal test. Rufus' vocals are always a pleasure, he posses amazing vocal power, stage presence and a magnificent vocal tone. Just as talented as his father! maybe not as quirky The PUC2 produces a very smooth vocal reproduction. No complaints, the PUC2 is really doing a great job on all music styles and variations. Smooth, detailed and musical, end of story. Its rare that a piece of HiFi equipment allows you to forget about the product and just sit and listen to the music, but the PUC2 managed this rare feat a few times during my listening tests. Very rare and special indeed. For me the PUC2 midrange quality is its #1 selling point and validation enough as to why I purchased the PUC2 and moved my AP1 on. I don't think this point could be argued on comparison. In the interest to remain objective I would like to point out on certain songs - I found the upper midrange and lower high frequency playback of the PUC2 lite to become a litle harder than I would like. However through extended listening I feel this is only really an issue on poorly recorded material and is a result of increased transparency through the applicable frequency spectrum's. HIGH FREQUENCY REPRODUCTION Well we have an extremely detailed performer here. The PUC2 has no objections showing you "everything" in the mix. Highs are quite extended, realistic and revealing. But they still remain musical, I will say however, if you like a more relaxed presentation 'in general' the Audiophilleo AP1 may be 'slightly' better suited to your listening choices, alternatively the PUC2 is openly honest, it says here "it is", but always with very decent spectrum balance and studio monitor honesty. For me the best analogy I can provide is, 'The PUC2 makes 16bit/44.1k redbook sound higher resolution!' Cymbals sound like cymbals using the PUC2, you laugh, but not all HiFi converters can provide this realism, as lesser units they retain too much grain and frequency distortion due to jitter/poorer circuit design. The PUC2 demonstrates obvious low levels of coloration and signal distortion. On high hats you can hear the high hat metal (Copper/Tin) making contact with its distinctive tone and resonance. It was truly an ear opening experience coming from the Audiophilleo AP1. High frequency details are never harsh unless the recording is, but a word of caution to those with bright HiFi systems the Yellowtec does present on the brighter side than neutral, simply due to its high levels of transparency, so it may challenge your system. Overall spectrum balance is very decent and jitter is not audible in my system, which in real terms equates to an enjoyable, realistic and transparent high frequency presentation. Neither converter really has the edge over the other here. Personally it would be a subjective preference selected through synergistic system matching. What I will say is the high frequency playback quality of the PUC2 is subjectively more truthful and realistic than the Audiophilleo AP1. Again on Diana Krall 'Best Of 2007' track East of the Sun (and west of the moon)" cymbal work is clear and detailed, but without any undue harshness. Cymbal edges are defined and clear, with no audible jitter artifacts. Radioheads album 'In Rainbows' track Reckoner is always a fantastic test for mid and high frequency quality. The PUC2 does an excellent job with this track. Tom Yokes vocals are as always haunting and beautiful. To be honest I can't think of a time this track sounded so good played on my system. Beautiful spectrum balance from the high frequencies down. Cymbal work is clear, atmospheric and cymbal tails have fantastic decay, even at decent SPL levels. The PUC2 impresses offering incredible decay on the high frequency tambourine While spinning, Radiohead tracks, 'Everything in its right place' gets a listen. The track kicks along with great weighted keyboard notes and kick bass drum. I notice the bottom end is particularly well weighted with a beautiful muted kick drum. High frequencies are very well balanced in line with the tracks overall presentation. As with the previous tracks I have played soundstage and imaging is extremely impressive, Tom Yoke delivers another great vocal performance and I just want to listen to the whole track it sounds so good. Ryan Adams track "Everybody Knows" which in all honestly is a great test attack across the whole frequency spectrum , is a difficult test for a detailed system. Some systems fall down becoming overbearing in the high and mid frequencies. Well the PUC2 did a fine job. Cymbal work remained composed and in control. leading edges were soft yet very well defined. Bass was very well balanced, offering great mid bass punch and weight. Such a great track. Next we have Crowded house's 'Best of' Album', track 'Weather with You'. A great test track, and one I know well. Cymbals are again detailed and display solid yet soft edges trails. Its clear to me at this point, the PUC2 renders a very well balanced sounstage and image. Noticeably more impressive than my Audiophilleo1. Moving on to Crowded House track 'Fall at your feet', WOW what a solid and hard hitting bassline. Seriously pleasing bass weight, with great tone and solid presence. I haven't heard this bass line so solidly presented in my HiFi system before, its a nice change. Neil Finn's vocals are also clear, well balanced & centered in the image - nicely positioned in a beautiful 3Dimensional soundstage. In direct comparison with the Audiophilleo 1, high frequencies are again noticeably more transparent, detailed and truthful. I believe both the AP1 and the PUC2 have something to offer with their different approaches to high frequency playback. However the PUC2's improvement in soundstage and holographic imaging is a BIGnoticeable plus in direct comparison with the Audiophilleo1. Just a note: In testing I have found the PUC2 'in my HiFi system' preferred a copper USB over a silver core USB variant. Spectrum balance was instantly better and bass weight improved. System synergy was noticeably better. BASS WEIGHT & TONE As I have already covered, the PUC2 has impressive bass weight and mid bass attack/dynamics. The units ability to present a truthful render of a tracks bass tone and timbre is second to none. Typically when testing bass tone I like to listen to older recordings, which are mixed in the 70's an era in which bass was not generally synthesised and it was rich with natural tones and weight. However this time, I decided to give my trusting test track Jeffs Buckley "Everyone here wants you' a spin, an amazing song which delivers insightful and haunting vocals and a bass and drum line that always impresses with its weight and authority. The PUC2 did not disappoint. Awesome bass drum attack, both ample in weight and strong in delivery and again nicely detailed bass guitar tone and definition. This recording really is a great music track and test track. Additionally the PUC2 delivers amazing decay on the snare drum, cymbal work is clean and presents with a dreaming delicate presence. Jeff's vocals sit ontop of the mix ever smooth with beautiful reverb and echo - sound stage is really impressive. Bjorks "debut album" track Venus as a boy, is another great bass test track, especially if you have large bass drivers or capable subwoofers in your system. It offers rolling frequency dips of bass delight, with great definition and weight. A favourite track to test bass with. The PUC2 shows great control. Bass is tight and delivered with good control. The rolling bass sweeps are presented with speed and balance. On Fleetwood mac "Dreams" I get goosebumps (cliche I know). Bass is driving, balanced in weight and full of tone. I love this recording and the PUC2 is up to the challenge. Stevie Nicks vocals are beautiful, sorry AP1 owners but the PUC2 wins here hands down, the mid range is really a step up in quality. The bass guitar delivers great bass depth, all bass note changes are clearly defined and bass and drum kick sequencing provides fantastic weight. Impressive, I listened to the whole track, love it. On Little Feat's 'Time loves a hero' track 'Rocket in my Pocket' the bass line is driving and has great mid bass attack from the kick drum. The bass guitar has lovely roundness and a vintage bass tone. Bass and kick drum sequencing provides nice weight and drive. "Red Streamliner" also presents the same awesome 70's bass tone and mid bass attack. The bass in these tracks remains well weighted and supports the spectrum balance on the tracks really well. The track 'New Dehli freight train', confirms the PUC2 does justice to textured & toneful bass. I love the intro on this track with just the bass, guitar and drums. The PUC2 really impresses with its ability to present each instrument with fantastic detail while retaining great spectrum balance, bass attack and overall musicality. If you haven't heard this album chase it down, its a classic. The keyboards on this album are also a great mid range test... In terms of bass weight, I find little separates the PUC2 and Audiophilleo. They are both very good performers. However the PUC2 wins when it comes to bass detail and tone and low bass delivery, the PUC2 digs that little deeper to provide that little bit extra, those special moments where you think, "WOW I didn't know that was on the mix." Without going overboard I truly think this product offers exceptional converter value. Along with the PUC2's great frequency reproduction capability, the units ability to reproduce a focused, wide, rich & holographic image is very good indeed. For those that appreciate a decent image & soundstage the PUC2 is noticeably more successful than the AP1, providing a more immediate/forward, deeper, wider and 3 dimensional image. The fact that this sort of HiFi equipment can be purchased for an asking price of $500-600 its a true HiFi bargain. A true indicator of the pro market pricing competitiveness. I have no doubt the Yellowtec PUC2 lite converter in an audiophile case would have an asking price of circa $1000 dollars.... So at the very least this converter deserves some respect and ultimately a listen. "If I have one criticism of the PUC2 its that it can expose to much of the truth, and at times runs the risk of being slightly analytical, presenting a less relaxed/more forward/detailed picture than the Audiophilleo AP1." "On some systems this will come across as a harder presentation" At the end of the day both the Audiophilleo 1 and the PUC2 are excellent performers. Personally, I could and have lived with either in my system. But for me the PUC2 will stay for the time being, 'until something better comes along'. The midrange reproduction quality of the PUC2 and its soundstage/imaging capability is exceptional and for me icing on the cake! However for those with more forward and revealing systems the Audiopilleo AP1 may actually be a better synergistic match, as the Yellowtec is substantially more revealing and slightly more forward in the midrange and high frequencies. For those with balanced source, amplifier and speaker setups the Yellowtec PUC2 will perform nicely, offering a playback quality step up across the board. I say give the unit a listen, it deserves at least that... SOUND Brilliant, An audiophile Secret BUILD QUALITY The quality is where it counts - On the inside. AESTHETICS Not for everyone, but very well finished PRICE V's RETURN ON INVESTMENT (ROI) It doesn't get much better than this ROI offering SECONDHAND MARKET Not well known, may prove difficult to move on in Audiophile circles The snob factor will invariably reduce resale return, when I find something better *All listening was conducted utilising a DIY PC running 16bit/44.1k redbook FLAC rips. Playback software consisted of Vortexbox (Linux), (Windows 7) PlayPcmWin, Foobar2000, (Windows XP) cMP cPlay, MQN.

  5. I recently bought the Lenehan Audio PDX Konverter from Petng as an upgrade for my Metrum Octave + Audiophilleo2 PurePower. Petng has kindly provided an GoldAero 6DJ8 tube (Austrian) and I've been listening to that. I don't usually review or write comparisons, but given how impressed I am by the Lenehan Audio PDX, I thought I'd have a short writeup about this DAC (and also ask for help for some repairs needed on it). Apologies in advance if my terminology is not making sense here, as I rarely write about hifi, I'm not 100% sure of the correct audiophile nomenclature. My setup is as follows: PC (Kodi WASAPI event) > PDX USB > PrimaLuna Dialogue Premium Integrated > PMC Twenty.21. I expected an incremental upgrade from the Metrum but in reality, the improvement was massive. I'd say going from the Octave to PDX is as much difference as going from a FiiO D03K to the Octave, the improvement is that pronounced! I was also worried my speakers, the PMC Twenty.21 would be the bottleneck, but surprisingly it has scaled extremely well. During initial listening (1hr), I instantly noticed the better detail and dynamics of the PDX but I also did miss the sweet and analog sounding Metrum. For the next few hours, the sound of the PDX really grew on me, compared to the Metrum Octave, it has this really mature sound about it, giving my music this deep and vintage feel. String instruments, guitars, violins sound alive and real, not exaggerated like on the Metrum. Bass is more prominent and there is more authority to the sound. Imaging wise, I'm not 100% sure where to place it yet, it might just be my ears trying to get used to the PDX sound or that I never noticed with the Metrum, but when listening to a few songs, particularly "In the Air Tonight - Phil Colins" and "Grandmother - Rebecca Pidgeon", the voice was all over the place. When I had the Metrum Octave with Audiophilleo, I didn't know it could sound any better. I compared the Metrum to every DAC that was available at local hifi shops and couldn't find anything strictly better. I know I am really late to the PDX bandwagon and people reading this would be thinking "that's obvious", but I really feel like this is the end of the road for me. I am thoroughly and pleasantly surprised by this outcome, especially considering I paid about $3k for the Metrum + Audiophilleo combo and less than $2k for the PDX (well, with 3 previous owners). This sort of explains why Greg Osborn said my Metrum Octave sucked. Well the Metrum isn't that bad, it's just in a totally different league to the PDX. I need help: I haven't used the coax input because I can't seem to get it working, so I haven't compared the USB input (HiFace Evo) to my Audiophilleo PurePower. Peter thinks it might have something compatibility issue with the Audiophilleo and suggested I try feeding it with a CD player. Speaking to Clay, he says it sounds like an issue with the SPDIF chip or the v3.3 wires feeding it. In the mean time, can someone please recommend a competent tech to take a look at the SPDIF input? Preferably Melbourne SE suburbs. That said, I don't need the coax input, USB sounds great as it is. It's just to satisfy my curiosity.
  6. Item: Audiophilleo 1 + PurePower Location: Melbourne Price: $900 Item Condition: Excellent Reason for selling: Going in a different direction - raising funds Payment Method: Pickup - Cash, EFT Extra Info: Recently factory serviced. Turned out to be a broken USB connector on the PurePower. The entire PP unit was replaced under warranty - it has only two hours use. Includes all factory supplied cables, including Wireworld Ultraviolet USB. 12V trigger power supply. IR receiver. BNC adapter set. Hardshell case for AP1. Pictures: See below for pictures. These don't seem to come up second hand very often. I'm surprised it hasn't sold. It is clearly better than using the USB input on my Metrum Octave MkII. I'm selling because I'm going in a different direction. All is in perfect working order. The clear coat on the AP has a few fine marks when examined carefully as would be expected after two years of use. As mentioned above, the PurePower is virtually new. Details: http://www.audiophil...iophilleo1.aspx http://www.audiophil.../purepower.aspx Listing price is only $150 more than a recently sold AP2 + PP combo. The AP1 has some nice features over the AP2. Aside from the slick display, there is digital volume, IR remote control, polarity inversion, bit perfect testing and a few other extras. Have a look at the links above. This one also comes with a hardshell case for the AP1 and accessories. Feel free to PM with questions.

  10. Item: Audiophilleo AP2 + Pure Power usb to spdif converter Location: Sydney Price: $750 + postage Item Condition: Excellent Condition (including box and all original accessories) Reason for selling: downsizing Payment Method: Bank transfer, Cash - pickup Extra Info: The AP2 + PP unit needs no introduction. It is one of the top usb to spdif converters out there. My original unit was purchased at the end of 2012. This unit however failed and was factory replaced. This is the reason there are two serial numbers written on the box. The current unit has never skipped a beat and has sounded top notch. There is a very small dent in the pure power casing shown in the photos. Pickup is preferred around the south west area of Sydney
  11. Hi, There's a lot of folk on here with wiser ears than mine...but I'm really happy with where I've netted out...in sorting out my system...and I'd not have got there without this forum, so, just in case this helps anyone else...I thought I'd tell my story.... I've had a meridian 506, audiolab p/q, monitor audio ma1200 gold, with audioquest midnight 3 cables and quartz (I think) interconnects for 20 years. And until this house...loved the sound. I listen to lots of classical. Some world. And less pop/rock. I love a lyrical/sweet/spacious/real/warm sound that doesn't push itself at you. For me the 'in your face' sound - which is so impressive for 30 seconds in a store...gets VERY wearing, very quickly. But...more and more of my music was shifting to the hard drive. Not least cos the Meridian was skipping on older CDs - so I copied them for safety. And... The Meridian clearly needs help. The room the hi fi is in is the worst I've had for years - cathedral ceilling. Hi fi on one side of the room (asymetrical) with windows/curtains down one side. Speakers practially on the back wall. And closer together than I'd like. The soundstage was narrow. The music sounded dull and lifeless. And the mac sounded even worse than the meridian. And - given that I now have to listen at lower listening levels (kids!) - all these issues were exacerbated still further. So - time to do something.... With one, perhaps unusual startpoint....the speakers were NOT to be changed...why ...because I have young kids and I'm not making the speakers a reason kids can't enjoy the living room...changing them can be a dream for the future.... So all the rules that say start with the speakers had to be ignored. In fact I started with cables...partly because I have been staggered in the past, how much difference cables make. Plus someone was selling AQ Cheetah's for $200 on gumtree. (I've sent them off to AQ in the US to be reterminated...and will doubtless find out in the process, if they are legit!!) I picked up a couple of other good cables too and played a little... Not loving what I was hearing....and more than anything, realising that if I wanted to inject some vitality into my system, it had to be more than just cabling - as it seemed that to get the vitality just from cables - which I did - I lost depth and weight...which was no good to me at all. Then I moved onto DACs....and everything I read on this forum (and a little elsewhere) suggested to me that the Rega route might be the best one for me...as though I clearly was looking for a bit more 'clarity/articulation' - I knew that if it got too dry and clinical, I wouldn't enjoy the listening anymore. And I opted to go for buying used...knowing that I can onsell for not much loss...rather than trying to audition in store...which is just hopeless for me....as you need all your kit...in your place... to really hear..... So I bought the rega dac from a SN member...(who was going on to try an M51). And I loved it. (And had a really good experience buying it from him too. Even to the point that he contacted me after the sale to make sure I was happy...) Much more emotion and space in the music than the mac mini on its own....but without making the sound too harsh or too clinical. For a Meridian lover...the Rega is a really good choice..... More playingwith the cables again....and now they were helping more than just 'changing'...I bought some more audioquest midnights too so I had separate runs to the top and bottom connectors at amp and speaker terminals. And loaded up the MA1200s with sand to tighten up the bass. (It's such a clever bit of design that.) And I probably would have left it there, but for an exchange of PMs with another SN member from whom I tried to buy a used audiophilleo...and was too late (it went in a nanosecond). And on the basis of that conversation...and realising that the difference between a used price on the audiophilleo and a brand new one is really very little.....I ordered a new audiophilleo from the US. (And may I say...everything about the culture of this site was reflected in my various exchanges with a gentleman called Philip at audiophilleo - he was fabulous - and had the boxes to me in less than a week!) I plugged them in this afternoon...and notwithstanding Philip's advice that they would take a while to 'settle in'...I am absolutely socks knocked off, can't leave the sofa, rapt in the sound of the audiophilleo. The Rega Dac, for me, was a seriously good/ lucky choice. Doing the four separate runs of the audioquest was good too - whatever the science between separating the bass and treble - really worked for me - and 20 year old high end cable is cheap as chips to buy. But, even though it came last...and therefore started from the highest mark...I have to say that the audiophilleo (plus Pure Power) is just amazing. (I bought the audiophilleo 2) I had an experience more than 20 years ago when I went to a hifi show and Linn were there showcasing an $50000+ speaker system that made classical orchestral work sound so real that I've kept a dream alive in my head that one day, somehow, I would find a way to get that sound in my house. (Without the $50k of course!) They even built a purpose-built building within the trade show 'hangar' so that we could enjoy the speakers without all the cacophony that typifies such events....but I digress.... I'm not saying that my system sounds (quite) that good. But truly...given that the source is a mac mini (running audivarna plus) and the speakers are 20 year old mid to bottom end (compared to what all the people on this site seem to have)...the sound uplift by the audiophilleo is simply breathtaking. Not breathtaking in that the Rega is lacking...but breathtaking in that it lifts the total sound as much again as the Rega lifted the mac mini. I'm as close to the $50000 Linns as I've ever been - in my house or anyone else's. And mostly thanks to a $1000 box the size of a pack of cards! I know everyone's ears are different. But it's hard to imagine music getting much better than this. Thanks to everyone whose posts I've read and who has responded to PMs. To Rega - for keeping it 'musical'. And especialy to Audiophilleo - for bringing the music to life. P

  13. I am using a SBT(EDO) >Audiophilleo 1 > Metrum combination, which works really well with recordings up to 24/96. Yesterday, I finally downloaded a 24/192 file from Linn records to test if my Metrum can go past the 176 mark. Presto.....the file plays, but the sound is in 'slow motion'! The SBT shows a sample rate of 192, but the Audiophilleo 1 display shows a sample rate 44. Is this simply because my Metrum DAC is limited to 176 and doesn't supporting high enough sample rates? Or is there something else going on here? Usually the Metrum dac's red indicator light comes on when it doesn't support a format....so I am kind of hoping there is another explanation for the 'slow motion' sound? Any ideas?
  14. Ive heard about USB isolators that are designed to free our DAC's from computer associated electrical noise that contaminates the USB cables. I imagine they might work with some devices (hopefully HiFace & Audiophilleo) but not others? work at some sample depths and rates but not others eg 24/192? decrease some problems but add others Does any one know: a model that works with audio USB devices? what it does to jitter? Thanks kindly for your help
