AC Power - two circuits better than one?


Reorganizing my system starting from the wall receptacles (rewiring is not a possibility) but quickly ran into a conundrum. Is it better to source power for my audio system from several different circuits or one dedicated circuit?

More info: I have three possible options. Two 15 amp circuits (1 shared with a couple of lights the other with several wall receptacles including a pc) & one dedicated 20 amp circuit (but with only one single duplex outlet). I have mono blocks, power amp, preamps, digital & analog audio sources, & digital HT gear.

Should I distribute my system across these three circuits or try & source them all from the single dedicated 20 amp outlet? If distribute, what kind of break down makes sense?

If this was me and rewiring is not an option, I would look into getting a power distribution center such as a PS Audio Premier and plugging into the one 20-A outlet and seeing if all my gear can be accommodated. It is always better, IMO, to limit the number of audio outlets to as few as practical to reduce ground loops and EMI/RFI.

If one power center isn't enough (monoblock amp draw, e.g.) then I would look to get another power center or an A/V grade power strip and plug it into the outlet without computers or motors on the circuit.

The advantage here is that you don't have to worry about phase leg anomalies (etc) because the power generators will scrub the power input.

But if rewiring is not an option due to cost, then my suggestion makes no economic sense because you can rewire for a lot less than the cost of one PS Audio Premier, let alone two.

Thanks again for your input folks! I will endeavor to load as much as I can onto the 20amp outlet & the remainder onto the 15amp outlet. The difficulty is just physical connection - too many things for too few outlets (in the wrong places!). At a certain point daisy-chaining power strips - & running long power cords - starts to get problematic. That's why I was considering connecting the TV & DVR into the out of phase 15amp outlet.

I was planning on connecting the audio gear via a Monster AV2000 SS & the HT gear via a Monster HD3650. I would prefer to connect the mono blocks & power amp directly to the 20amp circuit via PS Audio duets to avoid the power limitation problems of surge protection/conditioning...

Actually, I had an electrician in on Friday - but as I wrote in my original post, rewiring is not a possibility. It's a very old house & not mine.
