I received my 950/770 combo a few days ago and I also have a very audible hiss from my viewing/listening position which is about 10 feet. I tried watching a few movies and in some of the scenes the hiss was audible over the track of the film.
Setup consists of: Swan Divas with SVS sub panny RP62 OUTLAW 950/770 and outlaw interconnect Monster Power line conditioner
