I have a PSA Detect Power Conditioner and two AVRs in my HT/audio system, one as the main system controller, the other drives the front center and LR speakers. I currently have an AC3 PC connecting the Detect to the wall outlet and all other components are plugged into the Detect. I plan to get an AC5 next soon. How do I get the best bang for the buck, use the AC3 to the wall as now and the AC5 to one of the AVRs, or visa versa? Also, which AVR would be best served, the main system or the one driving the front channels?
