Dedicated power circuits

@invalid  say you have two lines a foot apart  through the studs every couple of stud spaces the  top wire goes through the bottom hole and the bottom  wire hoes through the top whole 

FWIW, I use a single run of 8 gauge terminating in a 4 x 20amp distribution box of hospital-grade Hubble receptacles. Keeps it simple.

Many will tell you anything beyond 12 AWG is overkill. Including electricians and people on these boards. But for the small amount of extra $ over 12 AWG, why not. Electricians may not like working with 10 AWG because it’s a bit stiffer, but it’s certainly doable. I used Shunyata receptacles, one feeding my Torus RM20.

If you are getting electrical work done for the dedicated lines, there is a lot of simple layout things you can do to improve your sound quality, as I learned by working with @kingrex.

He does this for a living, and helped improve Michael Fremer of Stereophile’s household wiring alongside Garth Powell of Audioquest. Not sure if he wants his name associated with his username otherwise I’d link the writeup on Stereophile - I’d suggest reaching out to him. All costs to implement his fixes were relatively low, and he worked remotely with my on-site electricians to ensure things were done right.

I can easily hear an improvement with the dedicated lines over my old lines which are still there as a reference.

Run each outlet in its own conduit directly to the box.  We use conduit in Chicago. 12 or 10 is fine for 20amp. I prefer stranded wire over solid. Any breaker box with copper busses is fine. I like the audioquest line of receptacles. They are well made and grip like the dickens. Also, I recommend the whole house surge protector that mounts right next to the panel. Just about everyone on this thread is spot on. Good luck.
