I have been experiencing the same system hiss discussed in one of the other threads, however, I believe the hiss is associated with the 770, not 950.

Whats happening to me is that with absolutely no external inputs connected to the 950/770 system (i.e. only the 950 connected to the 770 and the 770 connected to two speakers), and the volume set at the very minimum (-80db), I hear a very faint (but acceptable) hiss. But adjusting the volume from -80db to -79db immediately propels the hiss to a HISS (hiss=not so loud, HISS=loud ) in my tweeter, and adds a little noise to my mid-range speakers. Turn the volume back down and the HISS and noise remain until you either turn the 950 off or toggle to a different input.

Why do I think it’s the amp? The HISS is present when all connections between the 950 and 770 are removed (as per suggestion #2 in the 755/770 manual).

Is this a grounding issue?

Anyone else have the 950/770 combo with or without this problem?
