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

@audiodwebe,

Here is a good article on sound and power for your home if you decide to go with dedicated circuits for your audio system.

Maybe run an extension cord from the room with the good socket as a temporary measure?

Well, you have received lots of advice but I'll throw one more at you of a bit different nature. If you decide to create a dedicated circuit then pulling wire is plain grunt work that requires no special training. If you can access everything easily you can save a lot of money by pulling the wire yourself. Why pay an electrician to do menial labor? Just be kind and leave him plenty of wire to work with on each end. Especially at the panel. Oh, and please let us know what you find. I believe there is an issue on that particular circuit.

Get several cheater Plugs and make sure the AC ground is not connected. These are male to female AC connectors that you can disable the AC ground. Many times hum is related to to a ground loop between units. Even if everything connected to the same AC outlet you can still have circulating ground currents.
