It probably won't help. My experience is that ground loops are very difficult to diagnose and eradicate. I have tried power conditioners, RF stoppers, cheater plugs, etc, and nothing works, other than finding the offending piece of equipment.
I admit that I am skeptical about the value of power conditioners in general. But I think (hope) that most would agree that, whatever good they do, they do not particularly help with ground hum.
