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

Shut everything else off at the circuit breaker and still hum.  

I guess I’ll keep on living with it until I get an electrician to install a dedicated line.

Hope that will do the trick.

OP:

You still need this evaluated, regardless of a dedicated circuit. 

Also, keep in mind they do make dedicated DC blockers that are quite effective.

What exactly is on the branch circuit your equipment is on? Just the other outlets in the same room, another room too, sconces, recessed ceiling, Maybe I missed it if you mentioned it earlier so I apologize if that is the case.

When dimmers are off they are not really off and they are very pesky. Disconnect the power to them and see  what happens. If your unsure turn off your breaker before you detach the black wire at the switch..
