I have an isolated (separate) grounding system for my five dedicated outlets. It consists of three 6 ft. copper rods driven into the ground in a triangular pattern, and it's within 10 ft. of the outlets. I had the electricians install this as part of the dedicated "package" and so the extra cost wasn't much. It's connected to my dedicated sub-main panel with 8-10 gauge braided copper wire.
So, how does it work? I've disconnected the dedicated ground wire on a couple of occasions and could hear no difference in music quality/character. Still, for the small cost I don't mind having it there, and by doing it I found out that the main ground must be effective. Good Luck and Cheers. Craig
