Two totally different amps IMO. The BAT wins hands down. I have had a FPB 200 in my system and I actually own a VK200. My buddy here in town has a VK500 and owned several Krell amps. By far the best Krell was his FBP200. When he bought the VK500 he ended up selling the Krell. The newer FPB series IMO kills the KSA's. I really liked his Krell as it is very musical and smooth. Overall we both found the BAT better.
