I ran a dedicated 20 amp to my 2-channel room when we built our home. At time of build I was using a McIntosh MC452 and eventually migrated to a pair of PS Audio BHK300 mono's. I had them plugged into a Shunyata Hydra-6, which was plugged into the Nordost QX4; which was plugged into the wall. No problems and I often listen to it loud, very loud...when the wife wasn't home.
