Anyone listen to Zu Audio's Definition Mk3?


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

Spirit,

I think you have to explain what you mean by this, for context.

Phil
Phil, before about 2007, I really felt analogue was far in advance of digital. At the time I was running my Michell Orbe/SME V/Transfiguration Temper Supreme tt front end, and Marantz SA1 cd/sacd, into ProAc spkrs. My tt was warm and tonal, the cd thin and sterile. But even at that time I was aware of euphonic colouration from my tt, that even though v. attractive, definitely meant my tt was not truthfully neutral.
Then in 2007 I replaced cd with EMM Labs CDSA SE, and spkrs with Zu Definitions Mk 2. Suddenly my preferences changed 180 degrees: I so preferred to listen to digital, which had a natural analogue warmth, and my tt became a source of frustration as artificial warmth became highlighted by the Zus-still v.enjoyable, but I knew a change was needed.
Then 3 months ago I installed the Trans Fi Audio direct rim drive Salvation tt with it's Terminator T3Pro air bearing linear tracking arm. OMG! Real precision and neutrality demonstrated by digital was now present in spades on the new tt, with all the tonal warmth and transparency which is a hallmark of great analogue.
I just feel that the tt performance envelope esp in treble transparency is challenging the Def2s and the 4s will be a perfect match.
Btw, i have a separate thread recounting my experiences with the new tt in the Analog Forum entitled 'Trans Fi Audio Salvation Direct Rim Drive Turntable'.
Spirit,

If your location did not change since you've introduced system alterations circa 2007 and continuing, then I would have expected you to have distinctly different preferences as your combination of gear progressed.

A key point here is that you started with a preference for analog with a Michell Orbe in place and the change introduced being ProAc to Zu Definition 2 speakers. With the Michell being a suspended sub-chassis turntable and belt drive and the Definitions capable of putting more deep bass energy into the room compared to the ProAcs, it's possible (even likely) that the colorations introduced by the turntable were exacerbated by switching to Def2s. Meanwhile, moving from the unsettled tweeter in the ProAc to Zu, going crossoverless and upgrading your optical disc player allowed your ranking of relative objectivity to change.

Now, once again you've introduced a large change in sources and the design differences alone will alter perceptions. You've moved from a very fine suspended subchassis turntable with "relaxed" drive characteristics to a slate-plinthed suspensionless turtable with the urgent pacing of direct-rim-drive. That's a pretty radical change and once again, it's possible that in your installation not only does the TransFi prove less pervious to structurally-transmitted bass energy, I would expect its timing to sound more correct, and that it will deliver more of the dynamic burstiness that is also natural for Zu. In other words, the Salvation will be more like digital in its good aspects, while being solidly analog in tone, finesse and musicality.

Now, if your question is, "Are the Def2s obscuring some of the information the Salvation sends down the pipe?" Sure. But so does any speaker. After all, the loudspeaker -- even a good one -- is the most egregious contributor of distortion of all the gear in the chain, and it functions into an acoustic space interface that further influences it. Will Def4 resolve more of what your TT is feeding it? Yes, and I have no doubt you will recognize this within 13 seconds of dropping the stylus on wax through your new speakers. As I've written before: I can't think of a single way in which Definition 2 is equal to or better than Definition 4, other than used 2s being cheaper!

But it's not going to be just what else Def4 resolves that Def2 doesn't. That's appreciated and valuable. But for me the two most beneficial improvements are in the audibly tighter unity behaviors of the drivers working together, and that very much applies to the 12" downfiring sub compared to the 4x10" rear-firing line array in Def2. The second thing is that while Def4 doesn't extend any higher than Def2, it sounds like it does because the nano FRDs are so much more agile up to 13kHz and the Radian 850 compression tweeter is as beautiful as it gets above there. I haven't heard anything in a tweeter even remotely as listenable in supertweeter duty as this Radian.

And yet, the human brain is a hungry beast. You could buy $500,000 speakers and if that Salvation is delivering information as well as you say, then even a half-mil will eventually leave you feeling you're not getting something you paid for in the source. Definition 4 will be a leap in musical realism for you. Enjoy your Def2s while you have them and have complete confidence in Def4. In the meantime, none of this is worth worrying over.

Phil
Phil, your analysis is a very clear explanation of what I think is going on. It's quite a surreal experience to have all the positives of digital (stable timing and consequent lack of time "smear", image stability) with all the advantages of analogue that even the best cd replay can't approach (tonal density, soundstage transparency, microdynamics etc) in record replay for the v. first time.
Your detailed comments on the Def4s are really giving me confidence that cd, tt and spkrs will be performing as of their best, esp. the idea that all the drivers will be of a greater holistic match providing a greater dynamic seamlessness to the sound produced.
Beyond what Phil mentions (and, admitedly, this may be peculiar to my set-up) is that off-axis listening is markedly better with Def 4s. Plus they can be placed closer to the back wall.
