Oops!! Some hum at the dealer, but less than at my place. He is a guy whose knowledge/opinions on electronics I respect, and he is honest (therefore I trust him), and he feels the hum he heard was "typical" and not a sign of a 'bad' transformer. He suggested it not be sent back to the manufacturer, but put back in the system and see what happens. I hope I can get used to the hum (not heard when music playing) and if not, will give a try to the Humdinger or Emotiva unit. Anybody have any opinion re: effect of Humdinger OTHER than reducing hum, i.e., its impact on music reproduction? I suppose AVA and Emotiva would say 'none', but wonder if anyone has experienced anything negative from the Humdinger....
