Hello... I use a Monster HTS-5000 for my 5 two-ch power amps, and a Monster Power Bar 2100 for my two Marantz M-500 mono blocks, and the rest of my components. I was talking with the head electrian at Home Depot today. He has a serious HT and seperate 2-ch rig. To make a long story short, my circuit breaker box has 15A for the upper part of my house, and 20A for the lower part (family room) where my HT is. My ?? is, are my AC outlets 20A? If the breaker box says 15A, and you go ahead and change the AC oulets to 20A, what damage will it do? I learned a lot talking with this gentleman. Thanks!!
