The 2nd review on C372 noted the exact same problem with the volume control I had.... and there are multiple reviews that complain about the low quality pre-amp (though they don't specify whether the volume control is part of the problem)....
I know the reputation NAD has for sometimes flaky knobs and controls, I've just never seen it personally.
