Posted in Audyssey forum 2 days ago and never got any response so I figured I'd make a new post.
Now, Yesterday I called Definitive Tech and they said it's probably a bad Amp Board. Well this doesn't make sense as when I turn off Dynamic EQ, the Buzz Sound goes away. Tried this with Ford vs. Ferrari. Keep in mind I've had my Onkyo 5 years before I did the Calibration (performed Calib. just last week ) and never, ever had humming noise from speakers. Speakers after Calib sound 10 times better.
Then I called Onkyo and although they wouldn't or couldn't say it was a documented problem, the tech mentioned that they've heard of this humming issue from other people with the older Receivers and using the Audyssey 2EQ.
Then, called Crutchfield. Brad over there believes that it has to have some defect within the receiver.
So I'm going to research and get a new receiver in the next month or so. Don't know if I'll go with a 7 or 9 channel (have 2 DEF TECH A60 atmos on my BP 8060 that aren't hooked up) heard pros and cons on using.
DEf tech said Denon or Marantz is what Def Tech's recommends, but not ruling out Onkyo or Yamaha. I only watch moves- all kinds, sports and news channels.
