Installing a dedicated AC line

I'd like to plug my amplifier into an outlet with a dedicated AC line back to the breaker box. Any suggestions on which Romex line to use or other steps to reduce noise and improve isolation? What can I do between the box and the outlet to improve my system? I've searched some DIY forums without much help. Thanks.

"His comment to me was that the 12ga better matches to the current being pulled across the circuit, smaller diameter, less resistance, less skin effect. I'm not clear on the explanation, I just remember he was quite clear in his opinion, and I trust his knowledge about audio and electronics."

Skin affect at 60Hz?
