Hi guys. I have been doing alot of reading and have come to the consensus that I would be getting the vsx 45tx in the near future. However, now I was thinking that I could just get the 41tx, and spend the rest of the money on a good 2 channel amp for stereo. Would I be able to hook up an external amp to the 41 receiver without any problems, or would I need a seperate preamp? When playing the stereo, would the sub (hooked up to the receiver) still be in play or would sound strictly come from the two mains? Any thoughts on any of the above?
