Depending on your budget, consider this: I have friends that have systems with a separate 60 amp circuit for the audio with a separate breaker panel on the wall / in the basement / in the closet as close to the outlet as possible. From the 60 amp circuit box have 3-4 seperate circuit breakers depending on monoblock useage, HT equipment, etc. My friend has 2 monoblocks on 2 circuits, pre-amp on a circuit, and digital equipment on yet another circuit. He also used the AudioQuest brown power wire from this separate service to the outlets. His system seriously woke up from the power upgrade from everything on 1 15A circuit
