I have both. I use the Shunyata 8 for the front end equipment. I use three (3) RGPC in paralell to power the amps and subwoofers. I think the RGPC may work better with high powered applications. If possible, you should experiment with different combinatons.
In my home theatre system, in another room, I use a Monster HTS 5100 MKII plugged into a RGPC with excellent results: the subwoofer and amps are plugged directly into the RGPC, and the Plasma monitor, universal player, etc, are plugged into the Monster HTS.
