I just bought a Yamaha rx-v1400. I also have Energy Encore 5.1 speaker set. I have yet to hook it all up. I also have a set of bose 901's sitting here doing nothing. Can I incorporate them into the system with the preamp it has. I am a tad overwhelmed as to how I am going to hook everything up. I am also connecting my PC via digital optic and hopefull the xbox too! Arrrrrggghhh! Sould only take me a month to figure out. Does anyone have any suggestions to make my task easier?
