I heard it in Tampa connected to the big Wilson Watts through (i think) boulder amps. Sound as in a word -stunning! Quite possibly, some of the finest reproduction I've ever heard. Source was some very high rez digital files of music I was unfamiliar with but even at low volumes, you could hear right into the center of the recording and deeeep into the back of the soundstage. You don't often get to hear sound done this well. Might have helped that Peter McGrath from Wilson had just tweeked the setup in the room a few days earlier.
