If you can’t solve your problems with breaker assignments, etc., for whatever reason, consider an isolation transformer. The added benefit is over-voltage protection from an electrical disturbance such as a lightening strike or a transformer event.
Of course, this comes at a cost. First, they hum while they work, so they must be sited outside a music room. Second, some electrical inspectors don’t understand, and get tense or weird. Third, they aren’t cheap. But they do work. I have one in front of everything which produces signal: ESL power, amplifier power. I also isolate motor controllers, but that’s just silly old me.
A separate ground was mentioned above, but I would be wary of that option unless you have a dedicated subpanel to which ALL the audio is connected, and it will always be that way. Otherwise you invite a ground loop of heroic proportions. Typically the ground plate is supported by fresh water copper pipe, which does a great job (assuming a moist environment around the pipe, and of course, unless you have plastic!!!).
Plitron sells good transformers, bare and boxed, and they sell directly to the public.
