I had a cheap Sony DVD player (hate to fire up the PS3 just to listen to CDs) placed directly on top of my pro amp and that caused the problem. I'd be surprised if the Oppo does this, but given the large power supply in the amp, I thought maybe I was just subjecting some unprotected part of the Sony to EMF it could not deal with. An equally old - but much better - Panasonic A10 DVD player fixed the hum.

My explanation actually makes perfect sense if you have just the right right amount of knowledge mixed with a much higher level of ignorance on the subject. Try it! Works like a charm.
