For years I too have had a hum from my McIntosh MC207, and because of this thread and Ivans suggestion, I purchased the Emotiva CMX-2. The hum has finally disappeared both from the amp itself and through the speakers.
It worked by plugging MC207>Emotiva CMX-2>PS Audio Quintet>Wall.
It did not work by plugging Amp>PS Audio Quintet>Emotiva CMX-2>Wall.
So a big thanks to Ivan for the suggestion.
Hope it works for you Mouse.
