I have owned them for 18 years. they take a ton of power to sound good. I have them bi amped with a Citation 150wpc, analysis plus oval 8 wires and love the sound. tried classe and bryston amps as well and they were over the top in your face treble. I have plenty of bass with the power I have going to them. hard rock I am not a big fan of on these speakers but not what I really listen to at home.
these speakers have very good vocals and a realistic soundstage. Even used my arcam receiver to power to try it out and sounded good but not like with the amp. looked at the 803 d2 and 802 d2 recently and couldn't get myself to pull the trigger. Couldn't hear a difference to me, liked the look of the newer speakers better but
