New Electrical Circuit

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.

@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. 

@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 

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

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