Sub hum from baseboard heater

I have two sub amps on two different breaker that are causing hum when my electric baseboard heater kicks on.

One sub amp is on the same breaker, but the 240 volt amp is not. Both suffer from hum.

Is there anything I can do to remedy this with the baseboard electric heater without running long runs of wire between amp chassis to ground them?

Any other solutions?

I use a minidsp HD, so unfortunately unbalanced cables.

Help. This is annoying.

You could try the Emotiva Cmx-2? I haven’t but when I had your problem I was going to try that solution out. If you ever do, let me know if it fixes it for you, thanks.

What happens if you bypass the miniDSP? What happens if you lift the ground plugs on the sub amps and the miniDSP? If that's not successful, then a blue jeans cable isolation transformer will probably solve it and do so without any other ill effects. The Blue jeans isolation transformer is the only one that I've ever seen that did not also take away some bass.
