I am extremely happy with the sound. I run the system with a Denon 5805 receiver, and with the Audessey eq engaged, the Ultra II system fills the room with unbelievable dynamics and slam (from the subs). The set also sounds very, very good with music. I listen to a lot of hi rez music and the results are spectacular. The subs are also very tight for music, but still produce the thunder for movies.
