This system has zero power humm.

DVD,Coax,Stereo

Dead quiet on start up, no change with volume adjustment.

Play DVD, Pause: Definite Hiss with ear 1-2" from tweeter.
Volume setting has no effect, same hiss at same level.
Power off DVD player. Hiss continues. No change.
Power off 950. Hiss gone.

Not really a major issue but it does appear to be real. The 950 performs as well or better than any receiver or pre/pro that I have auditioned. Hopefully this hiss can be isolated or explained.
