New Electrical Circuit

I always say, " You don't know what noise is until you don't hear it anymore."

Wow mind blown. Thanks guys. I had to do this out of necessity but excited for the unintended upgrade. 

@fuzztone 14 is thinner than 12. I think you meant 10. 
 

FWIW I have two 20a dedicated circuits with 12awg romex. 
I like to isolate digital from analog 

@puffbojie I am an electrician, so I installed them myself. # 12 AWG RW90 wire, 20 amp Sqaure D QO breakers for my panel, and Cardas Plugs. The difference was well worth the effort. Dead quiet, larger soundstage, seemed deeper and wider, the presence felt bigger. 

12 gauge solid copper for a minimum.  14 is better but much harder to work with.

I use an Oyaide receptacle following a hospital grade one.  You need it tight. I didn't notice any sonic revelations but I do enjoy my music more.

Had to cut an existing gang box to get it in dere.

I'd run 20 Amps, which immediately requires 12 gauge wiring. 

At a bare minimum, use Commercial/Residential outlets, which now have to be Tamper Resistant (TR).  Relatively affordable ($4-5 each).

While your electricians are in there might as well also put in a whole house surge protector in the panel.

@hilroy48 The electricians have it scheduled for 15 amp circuit. So a 20 amp is the way to go? What about the size or type of wiring ?

Minimum 20 amp CCT , I run Cardas Audio 4181 receptacles. I have 2 systems with matching electrical feeds.

Cruze first audio, Maestro outlets. 

These are like a component upgrade. I'd used Porter Ports for years and figured they were ok. Maestros don't change the sound of your system. You just get more of everything. Type in "outlets" in the search bar, you'll get all you want to know about all the different brands.
