Hey Saturn5,

Was the hiss you mentioned coming from all speakers? I discovered the same problem 2 days ago, but only on my center speaker. Tried changing out the speaker, the speaker wires, the interconnects, the amp, but the noise remains and it's got me thinking about replacing the 970. I've had it for two years now and it's been a great performer, but getting it back from repair with any kind of hiss is no good for me.

When did you notice the hiss? I didn't use the machine for a 5-week period, and when I turned it on there it was.
