Well I'm upgradeing my Home theater and would like some advice. For a receiver i was thinking about either getting the Yamaha RX-V661, Onkyo TX-SR605, or the Pioneer VSX-1017TXV-K. I was thinking about starting small, and getting the Klipsch RF-52. Will any of these recievers work with this set up. Also my buddy has a pair of old speakers that still sound great but we aren't sure about the watts it will need. The rear of the speakers say 4-8 ohms, and from 10-175 Watts. Any advice anybody.
