Monoblocks out of phase on dedicated line

Am I on the correct path of having my 2 monoblocks out of phase from the AC dedicated lines. The difference is 1 to 2 volts at the most between them.

I see. Which phase should I use for my 3 dedicated lines? I measured both phases without any appliances on them and I get around 122v in one phase meanwhile the other phase is 124v/125v. Thanks

I just move my 3 dedicated lines to 123v-125v phase. The electricity in my apartment is very stable with the difference of +/-2v between phases even with everything off at the panel. I have a few PSaudio noise harvesters that I use to check for dirty electricity. Everything is pretty clean until I turn on my Kavent monoblocks, that is when the ps noise harvesters starts to blink. I got into this Stereophile fine tune article discussing monoblocks installation.

Anyway, thanks Elizabeth for your advise.
