I just heard a pair yesterday at my buddy's neighbor's. They were the big ATC's, he said they retail for $13k. Source was a blu-ray player, don't remember what brand, pre amp was a Rotel processor, room was smallish and oddly shaped, no noticeable treatments. Sound was astonishing!!! Unbelievably dynamic! Huge soundstage, tons of detail, but not bright or harsh. I was very, very impressed.
