Lots of Power, Features
Hiss in every DSP mode
I bought a unit last summer, and both it and its replacement (same model) had noticeable hiss in the DSP mode at moderate volumes and even with a digital source. When I used the 5.1 input directly (and had my DVD player do the decoding), it was quiet: therefore, my setup, TV, wiring etc, DVD player, power supply is NOT introducing this noise. There is probably something wrong the DSP chip or shielding.
That said, hiss is only noticeable in quiet program sections, and clearly not everybody is sensitive to it, judging by the number of people who claim their particular unit is hiss free. I actually wrote one of these people (who was rather virulent about his unit being dead quiet), told him how to set up the test/what to listen for, and he too admitted there was a hiss. Again, if it doesn't bother you, then great, you've got a full featured unit for a good price, but if a slight hiss does bother you, than you may want to choose something else.
