I like separate circuit cables because of the hot and neutral isolation they provide. In an environment like yours, a single ground wire would be preferred. It is acceptable per code, as I understand it (disclaimer: I am not a licensed electrician), to tie the separate ground wires together at the audio system. This would almost be as good as a single wire. Almost, because the individual loops between the audio system and the breaker panel can still support resonance modes. The difficulty is finding an electrician who will install exactly what you want, and not try to talk you into a subpanel. A subpanel, even if fed with heavy wire, defeats the isolation afforded by separate dedicated circuits with cables back to the main panel.
A metal conduit must be grounded, and makes a second ground circuit from the breaker panel to the outlet box. A metal outlet box will tie this circuit to the ground wire if you use any audiophile outlet I'm familiar with. Nylon screws and washers to mount the outlets would break the outlet-box connection. I'd prefer a plastic box, but I don't know if such are allowed with metal conduit.
