The YG Acoustics Carmel (I think) at $18k. Actually, it's the only YG I have enjoyed and this was my third time hearing it. And it's not bad. The aluminum cabinet gave off just subtle vibrations (not absolutely dead but deader than wood). The image was rock-solid as you would expect. The gentleman running the room was very gracious and smart.
Quibble (since they were the show's most expensive): I thought I was hearing compression during one of the Jack Johnson tracks. Source was computer, the Luxman amp had tons of headroom so I was left wondering if the speakers were just barely starting to strain. But still, this room sounded good.
