"I feel your pain."

Those kinds of grounding problems can really be troublesome. Some manufacturers use isolated grounds and others tie the chassis to signal ground, and so this can really be difficult to isolate. It's one thing if the system is for very high output and then the hum is masked. But when it will be used at low volume such as in the home, hum can be really irritating and difficult to solve.

Good luck with it!
