Neuance & Zoethecus,EMC-1UP & First Sound Preamp?

I'm curious, have you tried placing the hurricanes directly on the carpet? I ask because I wonder how much of what you are hearing is the benefit of the Neuance and how much is the detriment of the Zoethecus. (I'm a Neuance enthusiast, by the way, but I like controlled experiments.)

Yes, Drubin, the amps have been on the carpet and they vibrate quite a bit from being in the path of the bass waves. Not a recommended procedure... :-(
When placed on the carpet, the distortion causes rather unpleasant screechiness, especially on orchestral crescendos.

P.S. In my longer post, I said "the wood floor, being LESS flexible" when what I meant was "...the wood floor being MORE flexible." Of course, the wood floor IS more flexible, and it would certainly provide a less stable footing than the concrete, but with the Zoethecus, it was surprising how much it killed not only the vibrations, but the "life" of the music itself. It sounded like a bunch of people playing with no enthusiasm at all after a hard night out drinking (or whatever). I can't put into words how dull it was: I thought the amps had caught a "cold." Even when the amps were on concrete blocks, they had more life than on the Zoethecus.
One never know, DO one??
