I am running a Parasound 855 from the outputs. I have my Toshiba DVD player running into the DVD video comp and Optical 2. My XBox runs into Video 1 Component and uses Optical 3. Both of these run to the TV through the video component out. (By the was, I show no degradation in signal and it still looks fantastic) My DST3000 HD decoder runs directly into the TV and uses Optical 1. Right now I am only using composite for Monitor out to the TV. I am using AUX 1 Analog to hook up the audio for the cable TV input. I know it can't be the amp because all I do is unhook it from my Yamaha receiver and hook it to the outputs of the 950.
