Set it up (after a couple of hours) and am very impressed with the sound however not very impressed with the DVD PQ. I have it connected to my Panny PW5B plasma, and selected prog component on DVD. The picture shows slight pixilation on murky backgrounds, also is grainy and has significant shimmering on for example grilles of cars. I had a Sony NS 730 progressive component and the pic qulity on this was far better - no pixelation/graininess or shimering. Am I doing somethin wrong with the settings? Also the cable provided to connect the amp to the sub is not long enough - can I just replace this with any old longer phono cable? Cheers for your help.
