I may just get the 80's and if i have any problems i may just get a 3 channel amp to run the center and mains. I may be incorrect but i beleive if i get only a two channel amp for the mains it could slighlty change the timbre match between the mains and center. That's why i've been thinking 3 channel, or should i let my reciever run my center and just get an amp for the mains????
