I have similar problem . I opened up the amp and realise that the input is connected to teh amp board via a short signal wire which have plugs on both ends. By applying some force on the wire and the connection, i can simulate the problems. Later, i decide to tighten the plug by pushing it in snugly and the problems never return.
I think this is a "poor" design as most amp will have the input directly soldered point-to point to the amp stage.
By the way, I do have a buzz problems. I tried many ways and i am convinced that ground loop is the culprit though i cant really totally eliminate it. The key thing is to float your CD powercord; remove the ground and see what happen.
Hope this helps !
