New dedicated lines have high noise floor.


I just installed two dedicated lines for my system.  Each is on its own 20a circuit breaker.  I used 10 gauge hospital grade MC cable (exact same length) and Cardas 4181 duplex outlets.  I was expecting a quieter noise floor and better sound.  I have a 3x to 4x increase in the noise floor compared with a regular outlet nearby.  One of the circuits has a "crackling" sound.  For the best results, I need to put my amp and source equipment on a single outlet.  If I use both the sound gets worse.  Any ideas?  I need to have my electricians come back, but would like to have some audiophile wisdom for support.

pg62 put all your source equipment on one line via one outlet strip and put your amp on the other. Float the ground to your amps using cheaters.
Let's see how that works.
