My friend is a Audiophile and master electrician he said and I followed using first a awg 10 -20 amp amp outlet
3 wire, a week later he said try this a 4 wire dual ground
1 common ground ,the other a isolated insulated ground ,
that brought the noise floor even lower, after a solid 1 week breakin ad the previous week low level detail documented by 6 reference songs I use to compare it was a clear winner .
my integrsted gets plugged directly into the wall.
and hav3 a Siemens surge protection directly hook to my 200 amp service.
