if I was checking to this I would ask
do you know what 60 cycle hum sounds like and is that it ?
( i'm making a poor assumption your in usa, i shoulda checked)
older home with poor grounding?
flourescent light on the same circuit ?
are all devices plugged into the same outlet ? even subwoofer?
if you switch input on reciever does it quit ?
if you turn of reciever does it quit ?
if you disconnect all inputs on reciever does it quit ?
if you disconnect cable tv line does it quit ?
and last but not least
your next door neighbor doesnt have a large cb antenna on his roof does he? or have 7 antennas on his vehicle
well there's some food for thought
