@thankful, much has been written in various threads that answer your specific questions.
Here is an example that I found:
https://forum.audiogon.com/discussions/romex-and-breaker-switches
Depending upon the length of AC wiring you need to run, and the demands of your audio components I would suggest either 12/2 or 10/2 gauge wire, individual runs to each 20 amp breaker you run and ground according to your local Electrical code.
I’m not sure why the above post suggests medical grade outlets, I would not go in that direction because of the negative effect of various platings used that diminish and cause harshness with the sound. The FIRST Cruze Maestro Outlets are fine as long as you prefer their sound.
