Anyone listen to Zu Audio's Definition Mk3?


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

Glory,

>>Musical to you may not be musical to me but there is no way with the system you have built around the Def4 you can get better results than I have with my Def2.<<

You're welcome to that opinion. If you have a Def2 system, it's going to be pretty good even with the gear you've chosen. I'll only say I'd rather have listened to my own Def2 system, and more so still with the further upgrade to Def4.

>>Moral of the story is one must build, from the wall out, with SOTA gear to hear the Def speakers at their best. Having so so gear on a Def4 will not make it sound better than a Def2 with Nano drivers that has from the wall out HE gear.<<

I suppose that's the "moral" to *your* story. Who agrees on what's state-of-the-art? And what's the correlation to cost? And then what's the correlation to convincing musial realism in domestic reproduction? For as long as I've been involved in this interest, I've found the three quite weakly correlated, no less so today. I'll say that over 90% of all sound represented as "high-end" to me has instead impressed me as musically and aurally dysfunctional. Have you heard Def4? I'm guessing not. There are *many* combinations of gear absolutists won't consider "SoTA" that with Def4 will produce greater musical realism than Def2 -- even with HO or nano drivers -- such are the advances in total system performance. This is the paradoz of Def4: it is more revealing, more transparent, more dynamic and yet even mediocre CDs and LPs sound better in every respect than on Def2. You only hear in contrast how much Def2 you hear with that speaker in a system, compared to the marked and further neutrality of Def4. I think you will grasp this when you eventually upgrade. Until then, you're selling conjecture.

Also, a prior post hasn't made it to daylight. I mention in it that it's been years since I've used an NAD M55. In any case I make all my serious judgments from analog.

Anyway, we disagree. I have my path; you have yours.

213Cobra, and other users of the Def4s, can you fill me in a little on the 5 way sub bass adjustments on the back of the speakers. This obviously differs re the solitary volume control on the back of the Def2s.
What I would like to know is if each control is independent of the next, or whether adjusting one parameter affects the previous/next setting. If each setting affects previous/next settings, then there is a whole lot of never ending tweaking to be done. Or is each dial adjusted and set with an apparent correct setting for the spkr/room interaction for that dial, and no influence on others?
Spirit,

I answered this question in a previous post. The five sub controls are interactive primarily insofar as the outcomes of anyone one control's settings acoustically may (likely will) influence your preferences on some of the others. If you change the hinge frequency, you may want or need some adjustment to the PEQ or the level, or both, for example. The phase setting may be more benign to other preferences but even that can influence level, PEQ and hinge preferences. What I wrote in my prior answer was that I do not see the five tuning options as being unnecessary complicated nor preventative of finding appropriate bass performance reasonably quickly. The new control options are not so simple as having only one level knob, but are far less tweak-inducing than a full spectrum parametric EQ and X-over combination. I think Def4 is pretty easy to dial in, and the controls are sufficiently intuitive to be usable by both experienced and novice owners. The primary enabling or inhibiting factor is the user's awareness of what to listen for, or whether they have either an intuitive or finely-honed sense of what sounds "right." Unless, that is, you're measuring, have the gear, and understand what's actionable in the resulting analysis. Not to mention, how obsessive are you -- do you know when to quit?

Phil, if I knew when to quit, I would have put my wallet away when I paid c$15000 for my first high end system in 1996, and not gone on to spend another c$85000 with never ending upgrades (Zu Def4s pending)! Ha ha!
You're right re prev post, I just wanted to know if control settings were intuitive to get right one at a time esp if they interacted with other settings.
I do know another (non Zu) listener who has an outboard active amp for his bass module with v.similar controls who uses dsp shaping (behringer?) to get correct levels for his room, and wondered if this at all is a route to go down with the Def4s.
Have pretty much settled on the Gloss Black finish, may go from never ending sub bass adjusting to never ending spkr polishing!
I really value your no-nonsense attitude to combining engineering principles and listening experience in your final opinions-can you peruse a couple of items that fit between pre and pow amp and tell me what you think?
First is BSGT QOL, second is NEUTRALAUDIO X-DREI. Both have threads on A'gon in Amps forum.

213,

I heard the Def4 set up by Zu at a Zu party in Atlanta with all Zu wire and what I would call OK gear. Not very good results. Even installed my Lampizator Dac into the system and it didn't even begin to help the sound coming out of the 4. My 2,which was the Def4 pervious owner, far outran the sound coming from his system. The 4 will not out do a 2 with Ford Focus gear and I heard that to be true. My friend was there and when we got back to FL and heard my 2 he was in stitches with laughter as the 2 was so much better.

I find it very hard to believe you heard Atma/ Tenor amps on your Def and that they moved you away.......what Tenor amp did you hear?

You are a good salesman but you are not going to convince those of us that hear huge sound differences when upgrading to, yes more expensive gear.

You can try and explain this away but what we heard will not be forgotten.
