My electrician had a minor background in audiophelia enough to not smirk and the understanding that everything matters. He built a small sub panel ahead of the main breaker box specifically for the audio and home theater runs. Before the work I demo'd the amp with the stock power cord and the clock radio with jaw dropping affect.
The Utility upgraded from 100 to 400 amp service (for pool and hot tub) which came with a very large diameter cable to a new main breaker and a larger longer ground.
He used what he said is a better than what he usually used for breakers but I'm not sure what brand or model they are.
He did use Hospital grade Hubbell receptacles. Other than that both systems are star grounded into the same lines, no conditioning.
