Sorry XM.
I just saw this.
The hum was strictly from the AMP.
They have had the 7700 since Tuesday at 10 am. They told me that they would for sure be evaluating it the next day (Wednesday). This is Friday and I have not heard anything. I intend to speak to them today at High Noon.

Will keep you in the loop.
Thank you for your interest.
