Hi all . I am new to the Audio/visual world and need some information about my receivers . I have a 5.0 Mission system consisting of a pair of mx3's , an mxc and m70's as surrounds . I originally bought a second hand Nad T761 for my system and now have a Sony str dh820 . Id like to know if I could use the Nad with the Sony (and if so how ?) . Or if its best to rather sell it ? I am currently using my pc as the source with an onboard 7.1 ch sound card (through fibre) . Any information would be greatly appreciated . Thanks . Kelvin
