I have Klipsch Quintet III as my four surround speakers in my 7.1 set up. The specs say that they are rated for 50 watts(200 peak). I recently was able to get an open box Denon 3310 for $340, i just couln't pass it up. My mains, center, and sub can handle th 120 output of the 3310, but I am nervous about the quintet's. Do i need to go get new surrounds.
