Kevin to my ears and taste I found nothing better than the Verity Parsifal/Berning/Stillpoint at the Holiday Inn and Verity Parsifal Ovation/Nagra/Silversmith rooms in that order. The only other room close, in my opinion, was the Kharma room. My only issue with Kharmas is they seem a bit too reticent in dynamics and the soundstaging is larger than life but tonally they are excellent.
The openess, dynamic contrasts and tonality of the 1st Verity room was as close to the real thing as I heard, stunning sound and an ability to play any kind of music with aplomb. I think the size of the room helped with the prototype Berning amps really showing an ability to open up the speakers with pleasing results. I left the show with a great love of the Verity Parsifals, they are a quite refined design. I had a really tough time leaving these 2 rooms and went back at least 3 times.
I found several nice rooms, several that could have sounded much better with more careful consideration of set-up (Avalon/Gryphon comes to mind, the speakers were at least 15' apart and the sound was diffuse but it had more potential) many of the others rooms were nice but nothing else that gripped my attention like the above.
Best value and also superb sound, Charisma. YMMV
