I heard the 9's a while back and was under-whelmed. I heard about the 10's and went for a listen and was very impressed. I've heard more expensive speakers sound worse, and after the CM10's, I heard a pair of 804D's again, in an admittedly worse room (crowded with other speakers, to close to wall, etc), and thought the 10's are going to dent sales of the 804's!! The staging was wide, high, and deep, I was impressed. I've heard and liked the PSB Imagine T2's @ 3500, and the CM10's were better in many ways, if not all, and the Synchrony 1's at $5500 would be sweating too. IMHO, YMMV, etc, etc....
