I also agree that any audio equipment that is connected together by ICs should be fed from the same Line, leg, of the electrical panel.
I do respectfully disagree with moving all induction motor loads to the other Line of the panel. This can cause an more than normal unbalanced load on the electrical panel, the service wire feeding the the panel, and the load on the utility power transformer. By having all the induction loads on the same leg this can lead to over heating of the main Ac power electrical system.
I would suggest balancing the motor loads evenly across both legs as close as possible. Also I would suggest keeping the branch circuit breakers for the audio equipment a few spaces away from the motor load branch circuit breakers.
Here you will find how a typical utility transformer works. Notice for a 3 wire single phase electrical service only the unbalanced load, (amps), returns on the neutral conductor back to the source. The remaining balanced loads are in series. What that means is some of the flow of current traveling though the motor loads is also traveling through the audio equipment power transformer's primary windings.
