I have to agree with Scott and hope his comments put this issue to rest. I never noticed any hiss from my previous Parasound unit, in any mode, until I started reading these threads. Since I was still on the waiting list, I did a few listening tests with my Parasound unit and guess what? To my surprise there was hiss coming from my mains, in analog mode, that coud be heard at least 18 inches away. I didn't have a problem with this because I had been listening to the unit for 4 years and never noticed it. When I introduced the 950 into "my home theatre environment", the first thing I did was just sit back and listen for a while. Sometime later I did listen for hiss in analog mode and noticed that the 950 reduced the amount of his "in my setup" by at least 50%. Not only that but overall sound quality in all modes increased substantially. Not too shabby if you ask me.

Now, back to enjoying my 950 - didjdude
