I went on Sunday. What a kick to meet John in person! I told him how his speakers bring beauty into my daily routine. He set up a pair of Walsh 1000s fed by a Peachtree integrated (150 watts/side, internal DAC), and used a $15 DVD player as a source. The sound was good, and the fellow in front of me bought a pair on the spot. My son-in-law, who accompanied me, almost pulled the trigger as well, until he called my daughter, and that was the end of that.
But the rooms all suffered from an upper bass boom, and Ohm's room was no exception. I wondered aloud if moving the speakers a little further into the room would be better, but John's assistant said he had trieed that, and the positioning was as good as possible. I played a track from a PT CD that sounded lovely, lots of transient detail with no etch or excess brightness.
John also brought a lot of potted plants along (I am aware of their desireable acoustic properties). One of the simplest setups at the show, and one of the best sounding, except for the systems that DSP'd the room boom out. When you factor in the prices of the gear and speakers, I think Ohm's room was a standout.
To me, though, John is a legend in this business, and it was a thrill to shake his hand.
