![]() ![]() But in all honesty, I have not truly decided which I prefer. I previously ran everything through my Decware Ultra pre-amp but always wondered what it would be like to go direct. I recently added a ZSB switch box to allow me to go direct from source to ZMA. are the best three words I can come up with. And with the right combination of speakers and allied components, I can't believe that I don't have the best that can be - at least for my preferences. They are serving a new purpose now and fulfilling it well! The ZMA is magical. I still have and use my Monoliths and they are phenomenal with the ZMA as well. I have the exact same speaker & amp combo as you and having about a month on my new Omega SAHO's with the ZMA, I couldn't be more pleased. When you have a product predicated on quality built by a company with a genuine desire to serve the customer, there really is no other outcome - other than good. Glad to hear all worked out with the ZMA. Having worked in the non-profit conservation arena throughout my career, I just count my blessings people like Steve Deckert make such wonderful audio products that most folks can afford. This amplifier was a early retirement gift to myself. And after all isn't that what this hobby journey is all about? But to me what best describes this amp is the immersive listening experience you'll enjoy with decent source equipment and speakers. It's difficult for me to put the sound characteristics of the Mystery amplifier into words. It appears that the ZMA benefits from the best cables you can throw into the mix. I can just hear so deeply into the music now. The sound from my speakers really opened up when I replaced my Reality Cables with Zenwave's offerings (D3 & D4 interconnects and SMSG speaker cables). It is absolutely quiet in my system, has perfect tonality to my ears, and creates an insanely accurate 3D soundstage driving my Omega Super Alnico High Output speakers. Here are my impressions: The ZMA is an exceptional, musically satisfying amplifier. So the ZMA with stock tubes has sufficiently settled in and for the last couple of weeks I've been auditioning some of Dave Cahoon's (Zenwave Audio) IC's with my system. It's amazing how well memory works when large sums of money are involved.Īnyway, we'll get the amp back in the mail this week so you can finally start enjoying it. This is a classic example of how I have learned literally everything I actually know. When these two missing parts are installed, I always check them to be sure they work correctly, but when they're not there and the amp still reads hum at -72.4dB. Since the audio ground and earth ground are bridged together through the test equipment the missing parts would have non consequence during the QC process. Just goes to show that when you're obsessed with finding something wrong with something it seldom occurs to you to look for what is not there. Turns out we omitted the bridging capacitor/resistor that connects the audio ground to earth ground. ![]() ![]() I am pleased to be able to say that I have found the problem with the amp and less pleased to admit I didn't find it during the original QC process and the second QC process when it came back. I once had a hum drove me nuts and pulled every cable off every component, payed attention to how they were put back in place with as much non-interference as possible, and the hum was gone. ![]() It's possible just re-routing present cables may prevent these issues. As I improved my front end sources these let me really hear what they were dishing out, and I've never had any other noise or sound issues. This is a very good line of cables, using both the Oho copper and sliver wire (not silver-plated copper) for conductors, well-shielded, and cryo treated. I still have these in storage but I eventually moved to VooDoo Cable interconnects as Mark notes, first Evolution, then Ultralinear and then to Stradivarius and Stradivarius Cremona edition. I replaced them with Version 2 interconnects that I preferred, a bit more full-bodied and a touch warmer. I used Reality cables at one time between my DAC and amp, they're nice. I don't have a ZMA but use a Torii Mk III and have gone through some cables to find ones that allow my amp to be all it can be. ![]()
