I had everything plugged into a APC Backups Pro 1100 UPS and still got hum. Out of depseration I bought a Belkin Home Theater Line Conditioner PF 20 and was going to daisy chain it into the UPS but Belkin instructions say no. I then plugged the 804 and the sub into the Belkin with the TV and DVR connected to the UPS,,still hummin'!!!! I have tried changing the sub cable and just ordered some more from Monoprice but feel like I am just throwing money away. Returning the 804 to Onkyo doesn't seem to be working,,,,any more suggestions. By the way, I had a Onkyo 787 which was running fine but I wanted HDMI connects, which I got, along with a hum!!!
My suggestion is to do what I do -- realize the hum exists, but more than likely it does not effect real world usage. So just ignore it.
I realize some people it does effect more -- but with me, I can only hear the hum if there is dead silence from the source itself (ie. a point in the DVD film where there is no one talking or no music) AND if my volume level is set at -10 from reference or louder.
So for me that's not a big deal. I can live with it.
Do others hear it more easily in real world usage?
