Quad panel outlet - can I do one circuit on this?

I’ve never have seen an audio component with a 20 amp cord. Have you?

Yes, absolutely.

Audio Research, D’agostino, others. It’s not necessarily that they need the full 20A at 120VAC, but that the manufacturer recognizes the advantages of a 20A line, such as minimizing voltage drop. ARC used to ship preamps with 20A cords - obviously, no preamp needs a 20A line.

Power conditioners and iso transformers often come with 20A cord and plugs.

It is better to use two duplexes instead of a single quad for this reason:

With 2 duplexes, you have an improved ability to arrange power cords to mitigate interference and interplay. 

I was able to remove a persistent hum simply by rerouting cables and moving component positions on the shelves.

Yes. My Crown Studio Reference 1 Amp requires a 120 Volt, 30 amp dedicated circuit. See power cord below image 2:

Does your amp have a cord like this? 30 amps will run my hot tub!

No. See amp power cord below image 2 that’s the factory power cord my amp has.
