Can moving wire location at circuit breaker reduce hum?

The power line going into my music room will oftentimes make the amps’ transformers hum.  I’ve tried many things but have had no luck.  If I take any component that’s humming into a different room run on a different circuit breaker, the hum disappears.

Would swapping out the wires that go into the two separate rooms at the breaker make any difference?  Or is it more likely that one of the outlets on the circuit that goes into my music room is somehow miswired and is causing the hum?  I can unplug everything from the circuit except for my amp and it still hums.

Any suggestions on what I might be able to do short of hiring someone to run a dedicated line?

Thanks,

Mamoru

Hi

Looks like you have a pesky one. The way you described it is a little confusing though. Does the hum happen constantly or is it “oftentimes”?  Is the amp the only component humming or are there more?  You talked about “any component that’s humming”, what else is humming?  The fact that moving the amp to another room stops the problem tells you it’s not the amp. Have you tried different outlets in the original room?  To find out if the wiring is at fault, you can try a simple, inexpensive wire tester such as this one: Klein tool RT110 receptacle tester. Moving the wire should be your last result. Good luck.
