"Is your your audio system on a circuit with several convenience outlets prior to the system? If so, check the way these are wired. Sometimes electricians use the outlet devices as tie points for the wires coming in and going out the boxes. If the outlets are speed-wired, the stripped ends of wires are inserted into holes in the backs of the outlet devices and gripped by springs. This means you have a daisy-chain of these poor spring-loaded, knife-edge contacts, as well as every snap-off bridge that joins the two outlets in duplex devices, in series with your audio system's outlet."Al I think you have it....The fact that loads are connected to this branch circuit and as you know current will take the path of least resistance.
It probably would be a good idea to check all neutral terminations. He should not be getting any difference of potential between the neutral and the equipment grounding conductor.
I would also turn off the branch circuit and check the resistance between the neutral and the equipment grounding conductor. NEC says the resistance shall not be more than 1 ohm.
