  1. Further information: Relist as I had to turn a couple of potential buyers away due to not being able to in-person audition. I don't have boxes for these so interstate postage is not possible. 75W per channel. About 220-240hrs on the Mullard EL34 tubes. Amp was serviced locally by Hifi Exchange and tubes replaced. I have the old tubes that I can pass to buyer.
  2. These were purchased from this SnA member here: 75W per channel with 4xEL34 tubes on each amp. Lightly used to power my left and right mains for HT duties. Happy to demo for serious buyers. Weight is 30kg each.
  3. Item: Rega Exon 3's, with pre or without Price Range: Negotiable Item Condition: New or Used Extra Info: Looking for a pair of Exon 3's, hopefully in Melbourne, in as good condition as I can find. If there's a pre with them, will consider, but without is just fine 🙂

  6. Item: One pair of Perreaux Silhouette SX60M Monoblocks Location: Nanango Price: $500 for both (including postage to the eastern states, buyer to pay paypal fees) Item Condition: Excellent Reason for selling: Trying to make some space and free up a little cash. Payment Method: Pickup - Cash, Paypal, Direct Deposit Extra Info: Nice little monoblocks, 60wpc into 8 ohms and 75wpc into 4 so they are not powerhouses but they are quite respectable if used on speakers that are not too demanding. Both come in original packaging with original manuals and original performance printouts. Both come with power cords too but they are most likely not the original factory cords. These were Perreaux's lifestyle range of gear from about 12 years ago, no class D, all class A/B. Designed to be used with a passive pre so they should combine well with a Schiit Sys. Pictures: Yes I realize the pics are old, but they are relevant.
  7. Item: A pair of CONSONANCE CYBER 845 MONO BLOCKS Location: Ascot Vale, Victoria Price: $1800 (Firm) Item Condition: Excellent - These amps have been lovingly cared for however there are a couple of slight dents/marks on the side edge as shown in the pictures. They look far worse in the pictures than in the flesh and must have happened during our recent move as I had not noticed them until I looked them over for this add. Reason for selling: I am told that these are too big for our lounge room. Payment Method: Pickup only - Cash, Paypal, COD Extra Info: Over the years I cycled through a few amps, valve and solid state before finally settling on these. During this journey I found that I was very drawn to the Single ended valve sound, however, found their low power limiting. The Consonance 845's where the solution for me with class A, single ended, 28 watts. I currently have Shuguang 845B, National Electronics 5687 and Philips SQE88CC tubes fitted to the amp and will include the additional valves, shown in the pictures, in the sale. Due to the size & weight, (approx 30Kg each), a local pick-up only. Please note that I am happy to audition for serious buyers but I am firm on the price. these are outstanding amplifiers which present great value at this price. If I can't get this price my wife will just have to put up with them in our lounge Pictures:
  8. Hi all i am making a new pair of monoblock ampllfiers using nos brimar 6v6g,s in pushpull for the power,in the phase and preamp i am using nos russian 6sn7s with gold grids and british ef37a. the design is based off the leak TL12.1 instead of using a gz34 for rectifer i am using a lower powered rusian version of the gz34 mainly because of the cost. the 6v6 is in the 6l6 6f6 family and because the 6f6 is a kt66 by running the cathode ristors a bit lower and a number of other changes i can use a 6v6. the output transformers are the 20 watt altronics line transformers that i have talked about here and for power transformers i am going to use the beacon R08 its about 300 volts a side it might be a bit more i might use a choke but they will need to be a decent size and i don't have a decent size pair. thanks Bruno
  9. Item: CONSONANCE M800 SE EL34 MONOBLOCK (PAIR) Location: ALEXANDRIA / SUTHERLAND (SYD) Price: $1200 + shipping Item Condition: VERY GOOD Reason for selling: Surplus Payment Method: Pickup - Cash or Paypal. Extra Info: Includes all tubes inc. Tung Sol power tubes from Tube Depot. Original boxes and metal guards. Switchable from 75 watts ultra-linear, to 35 watts triode on the fly! 240V FOR AUS Too powerful for my application. Been unused pretty much since I got them from a fellow SNA'er. Very clean and no real marks to speak off. Perfect working order. EL34's sound excellent on mid-range, especially in SE mode. One of the amps has two marginally offset holes in front panel where the switches are. Visible in one of the pics. Have some other tubes as well if anyone is interested. Genelex Gold Lion EL34's x 4 (New), 6NS7's. Pictures:
  10. Item: 2 x Parasound Halo JC1 Monoblocks Location: Melbourne Price: $7500 Item Condition: 9/10 Reason for selling: Not used anymore Payment Method: Pickup - Cash, Paypal Extra Info: These babies have been well cared for since I purchased them from Simply HiFi 29/03/2017 as an Ex demo pair. These came with a 2 year warranty from the importer based in NSW and still have warranty to 29/03/2019. I have receipts if needed. I also have all original boxes and accessories for shipping if required. I had these shipped from W.A. to Melb with no issues. I believe current RRP on these are $8995 each. Pictures:
  11. Item: Auralic Merak Monoblock Balanced Power Amplifiers 200W/400W Location: Inner Sydney Price: $2,250 2,100 plus postage for both Item Condition: 8/10 (a couple of minor cosmetic marks on top plates, front plates and sides are perfect) Reason for selling: Freeing up some cash as moving house soon Payment Method: Cash on Pickup, otherwise Paypal, COD Only Extra Info: I had initially listed these as a package deal with my Auralic Taurus Pre Preamp, but have now decided to relist individually (Mark OKd this). These were purchased from Addicted to Audio about 5 months ago. They were floor stock and I paid them 2,800 bucks, however the price new was north of $6,500! They work flawlessly and produce a really incredible sound, which I would describe as powerful, precise, elegant and neutral, but far from col or clinical. Each Monoblock is rated at 200W in 8ohm and 400W in 4ohm (continuous power). Both are fully balanced. They incorporate an innovative hybrid design (half way between class A and D, at least this is my understanding), in which the advantages of class D amplifiers (small size, efficiency, zero heating) are paired with those of class A/B amps (high energy storage, massive power supply, and great control on all speaker types, including difficult loads). Each mono block has a linear power supply and 56,000uF capacitors array and can store up to 120J of energy, while remaining 90% efficient. This means they run stone cold even with low impedance speakers at high volumes. Each Monoblock has a circuit (which can be bypassed) that switches the amp on or off when a very low input signal is detected (or not detected), while keeping the output stage on at all times. This results in the amps being always ready to sound at their best (no need for any warm up time), while consuming virtually no energy when at idle. These have only balanced line in, and each of them has a low level line out that is controlled from the preamp and can be used to send the signal to active subs or more amplifiers. The exceptional quality of these mono blocks is confirmed in several reviews, including on SNA, where they were tested with the matching Taurus Preamp (that I am also selling separately). Here are some examples: http://www.theabsolutesound.co...c-merak-mono-power-amplifiers/ http://www.6moons.com/audioreviews/auralic3/1.html https://www.stereo.net.au/reviews/auralic-taurus-and-merak-pre-power-combination/ Specs and user manual here: http://www.auralic.com/download/MERAK_USERSGUIDE_R1.pdf Specifications Continuous Output Power; 200W/400W (8ohm/4ohm) Peak Current Output: >16 amp (40 ms) Frequency Response: 20Hz - 20KHz, +/- 0.5dB THD+N: <0.01%, 20Hz-20KHz@1W IMD: <0.01%, 20Hz-20KHz@1W Residual Noise: <50uV, 20Hz-20KHz, A-weighted Input Ports: 1 x XLR, Sensitivity: 2.2Vrms(RCA input requires adapter) Input Impedance; 10K Ohm Output Ports: 1 x XLR invert output ( for BTL mode) 1 x Cardas patented CE binding post Damping Factors; >800, 8ohm@1Khz Optimized Loads: 2ohm to 16 ohm Power dissipation: warm-up mode: 5W playback mode: 15W/450W (idle/max. output) Dimension: 330W x 330D x 70H Weight: 8.5kg I purchased them to drive my Magnepans 1.7, a notoriously very demanding speaker, which they did beautifully. I have now sold the Magnepans and do not require these anymore, plus I am moving to a larger house and I need to cover some extra expenses. The original boxes are missing but given the small size, contained weight and simple shape these can be packed up professionally and safely posted Pictures:

  13. Item: Virtue Audio ICEBlock M5001 Monoblock Pair Location: Perth Price: $850 (firm) Item Condition: Very Good. No mods, no repairs Reason for selling: Not suitable for my system Payment Method: Pickup - Cash, Bank transfer, Paypal (add 3%) Specifications: B&W ICEpower ASP500 Class D modules, as used by Jeff Rowlands, Bel Canto, Wyred4Sound, etc. Gary Dodd Tube Buffers 250w into 8 Ohms, 500w into 4 Ohms XLR and RCA inputs Pre-out for use with a subwoofer 270mm wide x 105mm high x 240mm deep Extra info: Bought them here on SNA couple of weeks ago and I was planning to use them with my ER Audio ESL3 electrostatic speakers. Unfortunately, it turned out that due to impedance characteristic of my speakers these monos are not a good match for them. I have contacted Virtue Audio, and received a confirmation, that these monos were not designed to work with speakers with such a tricky impedance curves as some of the full range electrostatic speakers have. Pity, as they are really powerfull, have "pre out" and tube buffer changes a lot. If only had a dynamic or hybrid speakers (previous owner used them with M.Logans) , I would keep them. Local sale preferred, but can post at buyers expense. (Don't have original boxes, power cables not included in the sale). Pictures:
  14. Item: Vincent Audio Monoblock Amplifier (1) SP-997 (Black) Location: Kew, Victoria Price: $250 Item Condition: Excellent Reason for selling: Not in use Payment Method: Pickup, Cash, Bank Deposit Used as an extra power amp channel to drive my centre channel when I was running a home theatre pre amp. 150w into 8ohm. Balanced and unbalanced inputs. Local pickup only.
  15. Item: Audiolab 8200MB Monoblock Amplifiers Location: Lara VIC 3212 Price: $2000 ono Item Condition: Excellent Reason for selling: It all has to go Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Purchased within the last year. Perfect working order. They didn't come with pins for the XLR inputs so there is a set of Cardas pins included if you want to use RCAs. I'm selling the entire system for now due to necessity so there will also be a set of Vivid Audio V1.5s, an Audiolab MDAC, and a Shanling CD3000 listed. I don't have the boxes for these so local pickup is preferred. Specs below. Pictures:
  16. Item: VTL compact MB100 monoblocks Location: blue mountains NSW Price: 2000 ONO Item Condition: very good Reason for selling: thinking of trying something different Payment Method: Pickup - Cash, Paypal( +3%),transfer Extra Info: the MB100s have a wide and deep sound - clear with heaps of tight punch. they will drive most loads comfortably with plenty of headroom. they are heavy and very well built- quite industrial. one mono is running the original VTL 5ohm output transformer, but the other runs a good quality but non-original 8ohm transformer.. i have listened to these extensively and can say that there is no variation in sound quality between the amps . if there is a negligible difference in audible output between them then it may be ironed out by using 12AU7s in one and 12AT7s in the other or via your pre but i have generally not found it necessary. these are 240V. 4 X EL34 XF2s and 4X 6CA7 EIs. i have included specific photo of scratch on one transformer .

  17. Item: Single-ended Tube Monoblock Price Range: $500 Item Condition: Used Extra Info: Let me know if you have one for sale.
  18. Item: Ayre MX-r 300 watt Location: WA Price:$3600 Item Condition: Very Good Reason for selling: Surplus Payment Method: Pickup - Cash, Paypal(all fees to be paid by buyer), COD Only Extra Info: All original packing and accessories.Note this is only a single mono (300 watt @ 8ohms) was used for driving a Dynaudio Evidence center speaker. Barely used a few hours.....has the upgraded boards. Pics Monoblock is hiding in rack behind center speaker.....can provide better pics on request....currently packed up ready for freight
  19. Item: Quad II 80 Monoblock Location: Canberra Price: 4880 Item Condition: Superb, Reason for selling: Long story short - Man can't controlled his urge and splurge on something called 802D3. Man got busted by his wife and got threaten with something begin with D and end with E and similar to 'DIE'. But man forgot to tell her (during the first confession) that his soon to be new love are hungry for power and has also secretly bought something called MC451 for his new 802D2. So, man has to sell all his old systems at a giveaway price before his new toys arrived. Sad story but true and I think everyone's here can relate to! Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: I bought this a couple of years ago, never use it until a pair of ESL57 came into my possession last year. It was a match made in heaven(at least for me). 4x kt88 in each block pumped out 80w per channel. The warm sounds gives me goosebumps every time. As been a bedroom system, it doesn't get the listening time it deserves. Extremely low hours on the tubes! Still RRP $14k+ Have all boxes and manual, can send at buyer expense and courier arrangement. Prefer local buyers though as it hefty in weights, something like 25kg each. Im happy to sell this and my ESL57 together as a package. Happy to entertain all reasonable offer. Will donate generously to Stereonet if sells here! Pictures: Its late now, after a session of scolding from the wife. Sleep on the couch tonight so can't access the bedroom for photo. Will do it tomorrow!
  20. Item: Antique Sound Lab Hurricanes Location: Mooroolbark Price: $2000 Item Condition: Excellent Reason for selling: Too many Amps Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Here are my Antique Sound Lab Hurricanes in excellent working condition. 200w in Pentode and 100w in Triode, running 8 KT88 in each block which can be switched out to 6550, KT90 or KT 120. By altering the tubes you don't get an increase in power but alter the sound signature as all bias stays the same regardless of tube. Pick up is very much preferred as they weight over 30kg each. Would be willing to drop off to pack n send for them to pack if required. Have original manual also Pictures:
  21. Item: Ayre MX-r 300 watt Location: WA Price:$4000 ono Item Condition: Very Good Reason for selling: Surplus Payment Method: Pickup - Cash, Paypal(all fees to be paid by buyer), COD Only Extra Info: All original packing and accessories.Note this is only a single mono (300 watt @ 8ohms) Pictures: Will come later
  22. Item: Stereoknight M-100 (100watt+ per side into 8ohms, or 200+watt per side into 4ohms - your choice) fully balanced design valve monoblocks WITH octet PrimaLuna KT-88s Location: Melbourne, Australia (inner northern suburbs) Price: $4200 ONO Item Condition: Almost perfect Reason for selling: Sidegrading (very reluctant sale) Payment Method: Pickup - Cash, Paypal, bank transfer. Pickup preferred (thus a buyer picking up will be given preference). Extra Info: Here are a very hard to come by matching pair (sequential serials) of StereoKnight M-100 valve (tube) monoblocks. I had originally purchased them off a gentleman here in Victoria, and since then they have been lovingly and sparingly used, as well as upgraded and some expense. They are in near perfect condition. They have solid aluminium cases (I've never seen a build quality like them - really!), and there are only the odd tiny marks. I have tried my best to photograph all aspects of them. Information can be somewhat difficult to track down, however for those in the know, these are built by the man now responsible for Audio Music (AM AUDIO) - Mr.Fang. I am very happy to say that he is easy to contact and will provide any information and support needed. He stands by his products, and they are massively over-engineered, so should last a lifetime! Here are some links to have a look at. Note that the StereoKnight site is no longer active, as the company is now Audio Music (AM), and most reviews and spec's are relating to the M-75 monoblocks. Advertised here are the much upgraded M-100's, which as I understand it were produced only towards the end of StereoKnight's reign. Some of you will likely be aware that these all were (and AM still are) distributed in Australia via Greg Osborn here in Melbourne. http://www.osbornloudspeakers.com.au/ http://www.audioreference.co.nz/brand/am-audio http://www.am-hiend.com/index.html And here is a review of the (lesser) M-75's (please note the spec's on the ones I have for sale here are different): http://www.dagogo.com/stereoknight-m75-mono-block-amplifier-review Also note that I have added a full octet of select PrimaLuna KT-88 power tubes (4 per side). These retail at $175 each (thus full set = $1400). http://magentaaudio.com.au/product/primaluna-kt88-tube-silver-label/ I bought these tubes off a fellow member, at which time they had very little use (he changed to KT-120's as I recall). Note that, having discussed with Mr.Fang, you could use KT-120's in these beasts, making over 120 watts per side. Wow. Not that you'll need more power........Note that the newer Tung-sol KT-150's won't work in these according to Mr Fang (but now we're just getting greedy!). These beasts, irrespective, will most certainly lend themselves to tube rolling, given how madly revealing they are! At night, they look like two small cities all lit up. Really cool. NOTE: I am also happy to do a deal on the full set of KT88's (and some other spares) I replaced which could be used as spares (Electron Tube KT94). Just ask! Here are the specs from the web (for the lesser M-75's): http://www.stereoknight.com/M-75.html Specifications (note that these have much upgraded spec's. Please contact Mr.Fang via AM Audio for specifics). Tubes: 1 X 6H30, 2 X 6922 4 X KT88 Power output: 2×75W (8? ULTRALINEAR); 2x 140W (4? ULTRALINEAR) Input: 1 x RCA, 1 x XLR Frequency response: 10Hz?60kHz THD: 1%(1kHz) Input sensitivity: 2 V Input impedance: 50 K? Output impedance: 8?, 4? S/N ratio: > 90 dB Dimensions: 500×330×240mm Net weight: 29Kg x 2 Power consumption: 550W maximum Full balance design. High grade 600W EI type power transformer, extra wide band C-core output transformer (StereoKnight signature). High end components (Nichicon and Hovland capacitor), parts (StereoKnight designed heavy duty gold-plated binding post) and wire (TEFLON insulated wire and Japan made POCC rectangular solid core copper wire) all the way. ZERO-NEGATIVE-FEEDBACK technology. ZERO noise: dead silence background. MOSFET voltage stabilization. High control power (75WPC or 140W at 4?), capable of driving a wide range of loudspeakers. Easily accessible individual output tube bias measurement and adjustment points on side chassis. Detachable IEC power cord, high quality gold-plated StereoKnight custom binding posts and RCA jacks. Full high quality aluminum alloy body construction, power meter in faceplate and acrylic enclosure cover design: sturdy built with art. I have been using these amps as follows: Pre - Wyred4Sound STP-SE Power - Stereoknight M-100 valve monoblocks (via XLR in true balanced configuration) - I preferred ~100+W into 8ohms compared to ~200+W into 4ohms, but other systems will vary. speakers - Osborn Epitome (approx 90dB efficiency) sources - various, including hi-res digital and vinyl I must say these amps are truly extraordinary. I've never heard more beautiful bass. They simply don't suffer from slow or muddy bass. They are glorious in this sense. Clarity is superb, and separation and soundstage blows me away. If you're a jazz fan, I'd look no further (your favourite female vocal will make you shiver. Start with a quality vinyl pressing of "What's New?" by Helen Merrill and you'll melt. Having said that, I have a very eclectic taste in music (from jazz to classical to indie rock to heavy metal to 60's rock and back again....) and these amps produce it all with aplomb! Anyone looking for high-powered (and yes, we're talking up to over 200wpc fully balanced into 4ohms if preferred!!), these are hard to pass up. They'll drive almost anything easily. For those in the know, any audiophile tube amps producing this sort of drive usually cost well over the price of these! They really do respond to a truly balanced end-to-end setup, so fire up that balanced Preamp and invest in some quality XLR cables (I preferred a copper/silver mix to all silver, however (as always) each system and ear is different)!! I have all the original boxing and packaging. I worry about posting, even with proper factory packaging, but can do if needed. Tubes may need to be removed and padded up). You will need to get your own power cords (although I can throw in some cheapies, however I'd recommend something to match their quality). I have been very loving of them. They have always been allowed to warm up prior to use (they really come on song after about an hour ideally). They will definitely benefit from a couple of heavy & solid isolation platforms to sit on. They certainly sound a whole lot better (especially mid range) with the PrimaLuna (silver edition) tubes, compared to the set of KT94's that came with them. All my gear runs off a power conditioner. Please note that the power output needle on (I seem to recall the right channel) one amp does not work. It was not working when I got them (I am the second owner), and does not affect sound of course. I have not looked into getting it fixed, however I am sure this could easily be done. I may get the opportunity to have it looked at next week if time permits. You'll note the little doors on the sides of each amp. They come off with an allen key (supplied), and you need a basic multimeter (I'll throw in with the sale) in order to bias each tube. There is a bias screw next to each corresponding power tube (see pics). It's really easy, and according to Mr.Fang you can decide your output preferences. These amps can produce a lot more power, but it's up to the listener what their preferences are. Notably, the PrimaLunas went in and needed very little (if any) bias adjusting (ie. a matched Octet!). http://www.primaluna-usa.com/tube-rolling These amps go very easy on tubes (if standard biasing is applied), so they should last ages. These monsters are big and heavy and beautiful: - around 30kg each - packaging adds 2kg each - size (each in cm) is 46w, 22h, 30w - colour is silver aluminium with clear perspex lids I will happily arrange for an audition only for those truly intending to buy (amps are currently not in use). I live in inner-north of Melbourne. Price will be formalised before this happens (I don't want to spend ages working through critical listening, only for someone to try to lowball me. I am sure you all understand (and I will negotiate on price if required and reasonable), but it's happened too many times before). I am always very light-on for time (it took me 3 months after having stored the amps to get around to this ad!), so please do your own research. Price is negotiable, however it reflects age, condition, use, rarity and a $1400 tube set! Don't let them pass you by if you've been thinking of high powered tubes but the prices have held you back. Given this sort of quality and the bliss into which you will plunge, they represent tube heaven at this price range in my opinion. Happy listening! Mat
  23. Hi, I need to run only one speaker but I'm worried if connecting only one speaker (using only one channel) to the amplifier is ok or not. I get monoblock power amplifier which seems to safer to me but I still have to connect/use only one channel of preamp. Can anyone explain the effect to amplifier when I use only one channel of Integrated amplifier or preamplifier?

  25. I know sometimes it sounds like a bit of a cliché when people say "the picture does not do it justice" but in this case it is true. The system looks pretty good in the picture but the gloss and colour of the timber just does not come across. The Redgum stack looks 5 times better IRL. I wanted to start this review with a little background info since there isn't that much info out there regarding Redgum components (and I did a lot of googling!). For instance, I am willing to bet that while you can get a fair amount of info from the Redgum website about their choice of volume control (individual channel knobs or single knob) but did you know that you can adjust balance from the remote, and then reset the balance to 50/50 at the touch of a button? What about the fact that there is an info sheet stuck to the base of each piece of Redgum gear that includes not only the model number and year but also the name of the buyer and the details of any personal modifications they requested? So if you're buying second hand each piece of gear tells a story. My RGCD5ENR for instance was initially purchased by Tony Wright of Sydney and there is a note that he planned to remove the front panel prior to use. Now I don't know Tony, and I guess I'm not likely to, but having a name to assign to the player makes things a bit more personal. (I can deduce one or two things about Tony though, the first is that he obviously likes his music and doesn't mind paying for good gear, the second is that he is no fool, he has vibration dampened the case with two rows of blutak stuck to the underside of the top panel, cheap and effective, very nice!) I have said in the past that the design of the Redgum cd players is a little odd, using a cd rom as a spinner is pretty interesting cosmetically, philosophically and practically. I have to admit cosmetically it does make the player look a bit commonplace, it is a definite let down after that gorgeous timber faceplate. Philosophically it makes me wonder just how seriously I should take all the talk of other manufacturers regarding mechanism stability, cd clamps and custom error correction techniques when this player sounds damn good without any of the above. Practically I love the idea of a cheap and easily replaced mechanism, but the lack of a screen telling you what is happening is a bit of a bugger which is why I use my Consonance cd120 as a transport and the RGCD5ENR as a DAC. Another thing I wanted to mention, the RG175 mono-blocks have their AC power socket very close to their external heat sink so there is not enough room to use certain types of power cords. If your power cord has a thick, round plastic end just behind the three pin plug (as many expensive power cords do) then the heat sink renders it unusable. It isn't a big thing but it was certainly something I noticed as I couldn't use my custom power cords. I believe the newer model (since mine are 2007 vintage) has the heat sink mounted underneath so this is unlikely to be a concern. And last but not least, Redgum uses Philips remote codes, (as do Consonance and Myryad and many others) so I only need one remote even if I switch cd players. Yeah, I know it means nothing to most people out there but for me it leaves more room on the armrest for cd cases and chocolate wrappers and I really appreciate that. I'll get into the Pre and monoblock functionality next, and I'll put up a pic of that info sheet I mentioned. Edit: And here it is.
