I have a BAT VK-6200 and I love it. I don't think I be upgrading anytime soon. I had and sold the following: Cary Cinema 5, Classé CAV 150, Krell Showcase 7, Threshold T100, Parasound A21, Sunfire Cinema Grand Signature 5x400. The only amp that came close was the Cary Cinema 5 which I highly recommend. The Classé was also very nice. I did not cared for the Krell at all.
