Je48 sounds like he knows his stuff! I'd listen to him! But I will add that I just got a Krell FPB-300, with a 20amp plug, and it came with a cord that has the 20amp connector for the amp on one end, and the other end has a standard 15 amp plug on it. I plugged it into my APC power filter, which has a gauge on the front to tell how much current is being used, and so far I've never seen it move, or even get to the yellow, never red. So in practice you can get away with a 15 amp circuit. But, after reading what je48 said, I'm also considering a dedicated circuit for it! Certainly a good piece of mind. And isolate it from the rest of your gear.
