I read through this thread. Well skimmed. Plenty of irrelevant discussions here. If the thing only makes a noise when changing the volume via remote control I don't see what the problem is. It is because you have a dual ganged pot with a dc motor attached directly to the back of the thing. Its not defective. It is just one of those things most people probably understand happens and don't care about. My Odyssey preamp does the same thing. It has a remote volume. The pot has a motor attached to the rear of it and when I turn the volume up and down I hear it through the speakers. \n\nFor the guys out there saying "well my so and so AVR doesn't do that" yeah, because it is a different technology. I am not saying every 2ch preamp with a remote volume control will do this but It is certainly not something I would worry about.
