I was lucky. When I began to install really good equipment in the basement room dedicated for music and theater, I installed a 20 amp dedicated circuit. I have never tripped the breaker and since it was new, there was no corrosion. I have always been impressed at the fidelity I got right off the bat, even with my old Denon receiver, then adding the M200s, then the pre-amp. It is truly a great recommendation and should take precident over expensive "power conditioners" and the like. Good thread. I am curious about others experience as well.
