Hi Joel; I put a dedicated AC system and ground in about a year ago, and yes it was a very worthwhile upgrade. I used 6 gauge stranded wire as it was already in place. The electricians connected the 6 gauge to a four 20 amp breaker submain, and then much smaller gauge wire to four Hubbell duplex outlets. For ground, I had 3 six foot copper rods driven into the ground within a few feet of the outlets.
One bad side effect of this dedicated system was a significant brightness in my system that was only cured by good quality power cords, ie I was hearing the "sound" of the stock power cords. Otherwise, music had a dramatically lowered noise floor, and became much more transparent. It cost me about $800. for parts and eletrician labor. Good Luck. Craig
