More than likely it's your setup ... the wiring ... the speakers ..... as it's unlikely the issue would present in two different model AVRs.

Sorry to ask the obvious, but are you experiencing "hiss" or "hum"? Sometimes these two can easily be confused. "Hiss" sounds like when the wind blows (Sssshhh...), "hum" is caused by a ground loop resulting in audible mains frequency (50 Hz in Eurpoe/ 60 Hz in N.America) through the speakers.

+1 to jd, I also do not think the problem is inside any of your AVRs. smile.gif

Don't wanna seem pedantric, but the job here is not to "put a separate ground loop to avr", but to get rid of it. wink.gif

Try this please: disconnect the coax cable from the TV set-top-box and see (hear) if the hum goes away. In majority of the hum cases the ground loop builds up between mains ground and cable TV ground.

When I had my own ground loop problem in my system the solution was to buy a Belkin power strip with coax protection. Some thing (or similar) like this.

For more on the subject you may visit the Hum FAQ thread.
