Your electrician will hate you but do use 10 ga. wire and also have him do 2 circuits. The 10 ga is very stiff and a pain to wire up but you only do it once and use the screw terminal on the outlets not the push on hole terminal . I think the upgraded outlets also make a difference I use Porter ports sold here on Audiogon . They are not crazy money like some and grip the power cords very tight.
Dedicated circuit to the sound system
Well, not exactly about cables..but close. A friend of mine is an electrician and I'm looking at having him run a dedicated line to the sound system. Is there anything I should suggest to him regarding the wall outlet and wiring to be used? Otherwise I'm sure he'll just go to Lowes and get the standard materials. Are the "high end" electrical wall outlets I've seen on the internet worth the $$...I was just going to use "hospital grade" outlets that have some sort of circuit protection built into them. I guess after this is completed I'll be looking to upgrade the power cords? The wife will be thrilled to hear about this project!
