I have both. I have a pair of mono amps on the Zoethecus; am waiting for the Neuance platforms for the amps. I have the Neuance under my preamp, the First Sound.
Interesting that others have suggested the Zoethecus adds "warmth." I observed that my system seemed "warmer" in the upper bass/lower midrange, but couldn't "dial" it out no matter how many tube traps I moved around.
Interestingly, although I had my CD player on the Neuance, there SEEMED to be vibration enough to mask the advantage of the Neuance, so I constructed an airbearing platform of MDF board and racquetballs (suggested on enjoythemusic.com) and found that the sound opened up immediately. Even a friend, at whose home I assembled it, commented on the new clarity in his system.
I'm certainly not suggesting that the Neuance doesn't kill vibration, but in this case, the homebrew airbearing platform was better in most ways.
HOWEVER, I still use the Neuance, as I said, under my First Sound. I'd try it under the amp, but Ken built it with a certain weight in mind, so I don't think it'll work 'til I get the actual platforms for the amp. Guess that means I have an extra Neuance platform at the moment. I think I'll try it again AFTER I place the amps on the custom built Neuances. Perhaps what's happening is that the Zoethecus is masking the dynamics that the Neuance shelves have in such great abundance. Don't know. But I'm certainly going to find out after reading this thread!!! I'll let you know.
