I am biased I live with Utopias but I auditioned both the watts and JM before buying.The wilsons are very dynamic and"spectacular" but I found them irritating and causing fatigue.The Utopia I auditioned with Boulder amps sounded great. I now drive them with the GryphonSignature Antileon and they are alive dynamic and provide a very rich non fatiguing sound.I listen to primarily classical music.
