Anyone listen to Zu Audio's Definition Mk3?


Comparisons with the 1.5s and the others that came before? Getting the itch; again......

Agear,

The less said about Gary's choices of expression in the prior inconsequential imbroglio the better. But there is a difference in civility of discussion between me declining to endorse Gary's amplification and cable choices (which is what he seemed to want) and his langugage, tone and the shop-worn "Ford Focus" analogy. I did plainly write several times that I had no quarrel with him believing his choices were right for him, and that it shouldn't matter to him what I think. My entire reason for debating the point was to refute the idea that buying an exceptional speaker like Definition 4 mandates a subsequent massive investment in state-of-the-art gear to realize their potential. That's a pernicious notion, IMO, that I resist no matter the brands involved.

On the matter of a Zu owner who auditioned Audion gear on my advice: I don't know who you are referring to nor the circumstances of their audition. There are only two people I know of in the US who actually bought Audion Black Shadow 845 monoblocks specifically, for Zu speakers. In one case, the gentleman was unhappy with very well regarded solid state amps many times the price of the $12,995/pr Audions. He bought the amps blind, on my advice, and his response was "this is the best sound I've ever heard from an amplifier" (I have the email). He did not keep them. The reason is, he is highly sensitive to and intolerant of noise in electronics. He doesn't even like to hear relays on turn-on. I had warned him as part of my recommendation that the Audions would not be noisy in an obvious sense but they would not be as quiet as his solid state amps, and if this was going to be a problem, we should consider other options. He wanted to try, having never owned a tube amp, let alone SET. Others who heard his system found the noise level of the Audion amps to be inconsequential, but it was his system, not theirs. He's now embarked on a search to get "that same Audion sound with solid state silence." So far, he's still searching and I'm searching with him.

In the second case, the Black Shadows are firmly ensconced in a two-systems household and the qualities of those amps are fully recognized and appreciated, with both Zu and two other brands of speakers. I know of several others in Europe and Latin America who bought these amps after reading my experience with them, and all of those owners are happy. Black Shadows, particularly tubed well, are not "overly colored." They do have middling SET noise (less than most, a little more than the quietest (Sophhia)) and while I plainly say that most push-pull tube and solid state amps will have greater bass discipline and precision, the Audion 845 produces well-defined bass that is convincing and easily within the realm of high-end sound. Still, others may disagree or simply prefer something else, and that's OK with me.

>>Do you use power conditioning on your Def 4 plate amps as well as the front end electronics?<<

I simply power my Def4 subwoofer amps directly from the wall. I haven't heard any advantage to power conditioning there, and my balanced power transformer for the front end doesn't have the headroom to add them. When I get a higher-capacity balanced power isolation transformer for power amplification, I'll try the Def4 Hypex amps also powered balanced; perhaps that will prove better than directly from the wall.

So someone with Zu speakers did`nt like a SET amp,big deal, choose what you like that`s all

Hey Dad read the whole thread. Then report back with a more balanced responce on what I was trying to convey.
Marc,

I haven't heard any one TT drive type make all others moot, in the way that SET + Zu has been transformative for me. And I know of no one who has directly compared everything credible. I have, btw, heard the Palmer but not comparatively. It's good. Whether, for instance, it's better than the Acoustic Solid Wood Reference which is also excellent, I can't say comparatively.

How people who have heard the Dobbins Beat would in direct comparison judge alternatives as different as the DD Brinkmann Oasis, the BD 47 Labs Koma and the EAR Disk Master with its no-contact drive system, would be interesting and, practically, anybody's guess. The difficulty of access for straight-up comparison points out the futility of seeking "best." In today's boutique world of TTs, you're buying flavors, not perfection. Have fun choosing!

I am in the process of switching from top tier SS (Mac 601 monoblocks) to Sophia Electric 845 SET monos. Note- these aren't the Macs of old and are far from slow, sluggish, and dark.

I receive the new amps this week, so hope to have some impressions for you guys in a week.

I have owned or tried in my system:

BAT 300xSE
McIntosh MA6600
Shindo Haut Brion
Triode Labs 845 integrated
AudioValve Assistant
Vac Phi 200
Shindo Montille
McIntosh MC601s
MasterSound Due Venti
Onkyo 9555 integrated
Audion Black Shadows (though had a prob with the amp grounding---so were uncharacteristically noisy)

I decided to punt the MC601s as they don't do nuance well. I believe i can give up some slam (and there is no better amp I've tried for that, period) for some nuance and more texture. That said, the Macs are phenomenal amps and do the 3d thing that usually is reserved for tubes only.

The Shindo Haut Brion had my favorite mids---nothing plays strings better, period, that I've owned or demo'd. However it was dynamically lacking- and Shindo monos are pricy compared to many alternatives. I will probably pick up a used Cortese some day for fun.
