I've totally forgotten how stunningly graceful and powerful the Harman Kardon sound is. I've had a couple of "flagship" receivers, but never have I enjoyed music as I do now. Music now sounds inspiring on my system. I'm using an HK AVR-320 in my living room and I literally can't stop listening to my CDs...I'm going on 6 hours of unproductivity. I've always liked the HT sound of the Sony ES and Yammies, but the HK holds its own w/ crystal clear quality sound at the maximum volume. I am waiting on the new Sony TAE-10Es preamp, but w/ the sound I am enjoying from the HK, I am no longer anxious for it. For use as a preamp or a receiver, you simply cannot go wrong w/ the HK. If only HK made a preamp again. Anyone else in love w/ the HK sound?
