+1 on what DH said. Likely some other offending player such as a cable or satellite box. You can even try just the coax cable first as that's often the most likely source.
Marantz AV7701
I am experiencing horrible humm issues with my 7701 setup.
7701 is connected via XLR to 5 mono amps. Combination of Bryston and Wyred.
The 7701 when connected creates a humm noise independently of volume. The higher the amp gain and speaker sensitivity the higher the noise. I have a suspicion there is some wrong with grounding or what have you?
All units are powered and grounded via a BELKIN Power Unit.
Any ideas? I am ready to ship the 7701 back but wanted to get your input maybe i'm missing something...
Thx
