Just got my 950 yesterday. Turned it on and the first sound I heard was hissssssss! The hiss is not volume dependent and is audible to about 6 feet. Does it in all modes - analog/digital/bypass. I'm gonna experiment with different settings, interconnects, power conditioners tonight. I've used a 2 channel PS Audio preamp and preamp out from an old Kenwood receiver with my current system and did not have any problems with hiss.

My system consist of Paradigm Studio 80 speakers, Acurus A125 amp, Denon 370 CD, Sony 360 DVD.

If I can't make the hiss go away I will most likely return within the 30 day period.
