What I just had done (still not hooked up to the outlets) is to have a separate 100 amp subpanel away from my main panel for the house and run four separate lines from it, 2 20 amp lines for my amps/active speaker crossovers and two separate 20 amp lines for my front-end components, one of which source component lines has an isolation transformer between the box and the outlets that I will use exclusively for my digital components. I originally wanted to put the isolation transformer between the main box and the subpanel to isolate it from the rest of the house's electrical system, but the electrician said it would not pass code because the transformer wasn't rated for 100 amps. So I figured that the next best thing would be to try to isolate the digital components from the rest of the system to keep the digital garbage from getting back into the rest of the system. Not sure if this is the absolute best way to do it, and ultimately might still want to isolate the subpanel, but this is the way that logically made sense to me. I'm interested in seeing other responses to this thread.
