Just bought a pair about a week ago and I must say I am loving them! I am using them with Black Ice F 360 Pre and Zu Def. IV's They are smooth and warm sounding with great dynamics and slam. . Not sure how much warmth the F360 adds? Forgiving of bad recordings. I feel the reviews that are out there are pretty much spot on. As efficient as the Zu's are they can also take a lot of power. I have driven them hard and the amps have only gotten warm. I believe the first 20 watts are class A I would be interested in pairing them with their new digital preamp but at this point I am content. Finally!
