  1. Past hour
  2. Well, one needs to have a good excuse to have more amps, lol.
  3. Will keep an eye out thanks. Using one of these with great results. https://www.earyoshino.com/868/
  4. Hi All, "U" is for Uriah Heep, Sweet Freedom
  5. Haha..tubes require so much pampering...but I guess it's worth the effort😁
  6. Hi Ladies and Gents, Newly joined member here. Looking to get back into some old school 2 channel stereo gear to go with some vintage B&W speakers I have for a bit of nostalgic listening. Looking forward to getting more in depth with it. Happy Listening Kind Regards.
  7. Yes this is consistent with everything I’ve heard about them. Great pick up. The preamps come up very rarely so if you see one grab it. Or did you get one already
  8. Thanks Al! Yeah I’m just waiting on some new sanding discs as I wanted good quality as not to mark the veneer. Then they will get the same oil treatment. It takes about 6-7 coats to get a really nice colour/finish. That takes days to allow drying etc. I prefer the oil finish as you can feel the natural feel of the wood. It smells nice too. Hopefully we can have another GTG soon. My BBQs need a workout as much as the Hifi. Would also be great to see some old faces.
  9. Great amp. I have one myself. My summer amp, when my tube amps go into hibernation.
  10. It's happening! Shipping Sep 27th.
  11. Your photos remind me of these horn speakers I took while holidaying in Korea in Dec 2017
  12. Do you mean tubes in the pre-amp stage versus tubes in the amplification circuit? @aussievintage suggested that die to the proximity to the source, the pre-amp tubes have the ability to provide a greater impact. Or am I misunderstanding what you mean by "power tubes"? t
  13. love the progress Jakey. you love to do these things to fine detail and expect these will be an absolute treat once done great project ! love the new wood finish of the plinths, were you going to do the rest of the speaker the same ?
  14. Incredibly neutral and transparent class A preamp. It is in immaculate condition. Specifications: _ Fully balanced class A design built by discrete analog stages without any OPA or coupling caps in the signal channels. _ Non- feedback ACSS analog output stage. _ Uses three R-core transformers (135W total) with separate power supplies for the digital components and right and left channels. _ More than 45,000uf audio grade NOVER capacitors are used to ensure ample and smooth power delivery. _ A total of 8 groups of high-quality class A parallel PSU's, four double-stages for dedicated DC supply. To achieve a high S/N, the control circuit is powered with separate regulators. _ Uses high grade parts and exactly matched transistors. _ Four-channel 99 steps digitally controlled relay-based volume control avoids channel imbalance and improves sound quality. _ 5 analog inputs: RCA X2, XLR X2, ACSS X1 _ Preamp output: XLR / RCA / ACSS _ Memorizes all settings and resumes the last settings when powered on. Further information: Master-1 is a true balanced design applying the newest ACSS design which can improve the XLR connection to sound as good as the ACSS connection. They seem complex, but in fact they are the most simple design the world has ever had, their a lot components to process the power supply. The simplest and shortest signal journey brings out the most neutral and least coloured sound. Master-1 applies ultra-low distortion single stage ACSS amplifier and soldered directly on the motherboard. It is a fully class A preamp and applies class A power supplies. The ACSS is a non-feedback technology made with discrete amplifiers. Most people know the global feedback design can offer better specs in test measurements, and non-feedback can't do well in test measurements but can offer better sound for the human's ears. Here is a conflict of the classic circuits. But the ACSS opens a new field, it can offer a least coloration sound which is more neutral with very low distortion and high linearity. So it can retain the dynamics, detail and neutral sound but not sound bright or harsh. All signal gain is in current, all transistors work in class A mode. The XLR /RCA output buffers are Non-feedback, for low impedance, we applied a two-stage parallel connection, the output impedance is only 10 ohms. Master-1 has all components of four channels exactly matched before installation. Power supply: Three special transformer are used to supply power separately for the audio and control circuit. Master-1 uses 8 groups of high-quality class A parallel connection PSU, four double-stages for dedicated DC supply. The class A parallel connection PSU has very high input impedance to avoid pulse through the PSU from affecting the preamp and low output impedance with very fast speed and high linear, so it is a very clean power supply. Master-1 applies two linear PSUs for the display and control parts, avoid the disturbances through power line from affecting the amplifier. Input/Output: Master-1 can input not only XLR balanced signal or RCA unbalanced signal, but also the top-grade ACSS current signal. It can also output RCA signal, balanced XRL signal, ACSS current signal to the power amplifier. Using RCA input, Master-1 can convert to balanced ACSS signal and output real balance signal from XLR and ACSS. Master-1 can output RCA, XLR and ACSS at the same time. The input channels of Master-1 adopt separated shielding method. When switching, the idle signal lines linked to the equipment and the ground wire are completely disconnected. The idle input ports of the equipment are shielded. In that case, the sound quality won't be affected even with more connected equipment.   Volume control: The volume control is also different from conventional technology. Conventional volume control technology is the volume control implement in the analog amp input stage through a volume pot to reduce the signal . The volume pots quality effect the sound quality direct , the low quality volume pot cause lost the detail and channels imbalance cause the soundstage distortion . Even the high performance volume pot still cause the detail lose. Whatever quality volume pots, must cause the S/N worst . But in the Master-1 , we applied the I/V conversion volume control , the volume control just a variable passive I/V conversion place at the ACSS amp output, where the output is the current signal, not the voltage signal. The volume control is I/V conversion, and the volume depends on the current (I) conversion to the voltage (V). (Like R-2R D/A chips output passive I/V conversion) It can keep the signal frequency band flat and not lost any detail. It can't degrade on sound quality in every volume level . After the volume , there are four groups dual FET non-feedback buffer output stages offer the very low output impedance. The volume control quality is much important in the real balance gear . It must guarantee the four channels signal control exact to achieve the performance of the real balance gear . If the cool and hot of the balance signal can't guarantee exact, the balance output will has large distortion cause the sound quality and performance even much worst than a single end gear waste the balance gear design and the cost. In Master-1 is applied a four channels digital control relays based volume control. .Master-1 has total four channels through changing the DALE resistors to control the volume for avoid channels imbalanced ,achieve the best performance and sound quality of the gear. This preamplifier allow users select between 99 steps exponential characteristic volume control and 70 steps linear characteristic volume control, whatever volume control allow users smooth to control the volume level . While change the volume, the different relays break or close, it may had slightly switch sound on output and disappear while stop change the volume. Shield: Master-1 has complete separation of left, right amplifier channels, power supply, and transformer. It uses heavyweight all-aluminum alloy chassis to prevent the eddy current of transformers from interfering on circuit board. Components: Uses all audiophile grade components, including DALE resistors, WIMA & SOLEN caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets (Neutrik ) and gold IEC socket.Master-1 all parts of four channels had exact match before install.
  15. I, erm... like it. Pretty funky. OK - I only just found this thread too - probably due to @cafe67 finding the Fender ltd edition and posting it. I have had the Ultradeck and Mastertracker cart since January this year. It's the best MM combo I've heard to date. I'm starting to struggle a little with the setup I have. I don't think there is necessarily anything severely wrong, I just think I may have uncovered some compatibility issues in my vinyl stack and looking for ideas. I started out with a Rega P3/Elys 2 MM cart and a Rega Fono feeding a Musical Fidelity M6si amp through Chord RCAs. It was a perfectly adequate setup. I can't say anything bad about it, but there was nothing exceptional about it either. It was a consummate setup that did everything acceptably. The evolution then started. The Rega P3 went and the MoFi Ultradeck/Mastertracker came in. Significant life breathed into much of my vinyl catalogue. It's a rock deck through and through. Fast forward 6 months or so and I acquired an AVM P30 pre-amp from @evil c; a gentleman amongst men, for sure. It was certainly a step-up from the Rega Fono. Better separation and soundstage; finer detail too. Then swapped-out the Chord RCAs for some of Bill's Western Electric RCAs which resulted in a tightening up of everything - I'd describe it as more grip - attack, sustain and decay were much crisper and more real. Last of all, a recent issue with my 18 month old M6si resulted in a full-refund (issue was with compatibility rather than an actual fault with the M6si) and I took the opportunity to apply that against a McIntosh MA352 integrated amp. The reason I mention this is that I now have 2 points of comparison: 1. MoFi into AVM P30 to MA352 line-in using Bill's RCAs for both links; 2. MoFi direct into the MM input on the MA352. I wished I hadn't tried the MA352 MM input. MM cartridge capacitance is configurable on the MA352. The MasterTracker is nominally 100pF so I set the MA352 MM to that. The AVM P30 is not configurable, it's static at 220pF. I use a fantastic 1982 original Aus pressing of Michael Jackson's Thriller as a reference. I'm familiar with it and it is great material for testing too. Broad vocal range, plenty of bass and some higher-frequency extension on some tracks too. Listening to the opening track, Wanna Be Startin' Somethin', there is a brightness and sibilance at the top-end (hi hats especially) with the AVM pre-amp that is tamed when I go through the MM input direct on the amp. This brightness is repeated on other recordings too, although it only becomes really obvious based upon how reliant the track is on such percussion. Any ideas on things to try to provide further conclusions without steaming out to buy a phono stage with user defined capacitance, or going MC and all the expense that entails (my investigations unearthed some articles explaining why capacitance really only affects MM)?
  16. Yesterday
  17. I could be shot now but I find the difference between small signal tubes can be subtle compared to the bigger power tubes
  18. Hahaha... Iron Maiden. Seventh son of the seventh son... @08Boss302 brings back childhood memories.
  19. I am a devout audiophile and look forward to browsing through this site.
  20. It was driving me nuts because I have always really enjoyed the Vincent. It was like the sound was under water. I finally decided to check everything and found that I had the polarity reversed on the left speaker. Corrected it and now it is sounding awesome like I remembered. Probably connected it wrong because I was frustrated with smoking the R8 again. I have rolled a number of tubes for the 12AX7 and found that I liked the new JJ E83CC best. For 2 years I had trouble with intermittent static randomly from both channels and kept replacing the 6N1P's and the problem would be gone for a few months. Turns out the tubes I was getting had very corroded pins. I finally ordered a pair of gold pin 6N1P's back in early April of this year and I haven't had any more problems with it.
  21. Unlike any solid state amp i have heard so far. It doesn't have a sound it just lets the music flow into the room like a good tube amp. Quite uncanny.
  22. A superb musician. His work with Marillion is legendary.
