Does anyone have an info on this model reciever? I may be purchasing it used in the near future to replace an older Sony Pro logic reciever. I'm curious to know if it will have all the necessary inputs/outputs for future upgrades to my television or other components. I already have 2 sony 200w tower speakers, 1 sony 120w Center channel, a subwoofer that only connects with bare wire and am in the process of purchasing new rear speakers. Also From what I've seen on the recievers that I have looked at they only have a subwoofer pre-amp connector, will I have to buy a new subwoofer?
