ground loop questions


I have a ground loop the hum from which I can completely eliminate via cheater plugs on my amps which is where the hum comes from.
I want to try wiring a second dedicated outlet to determine if plugging my amps into another circuit will fix the problem.
My questions:
Is it safe to test this idea by using an extension cord on one of my monoblocks to another circuit?
With monoblocks do I need a separate circuit for each of them?

sounds like you currently have youw monos pluggged into a duplex receptacle...this is causing your loop...yes, best bet is to run 2 dedicated lines and receptacles, and plug 1 thing (in this case each amp) into it. using a heavy gauge ext cord should be fine, but be sure, the longer you go, the heavier you need...just how long do you need. I would run the line regardless...it will not only fix the loop, but also improve noise floor, background noise, details, the usualy improvements.
Be sure BOTH lines are on the SAME phase.For monoblocks. Your frontend and digitail you can seperate
I don't understand what it means to have both lines on the same phase. Does it require making an extra wiring connection? Can you explain?
