Whats is best amplifier for 5.2.2 setup with ( RP-8000F ,RP-504C , svs pb 2000 pro, svs pb 2000 pro) . Currently I have Yamaha Rxv683 . Can I use Rxv683 will there be any degradation in sound quality or damage to speaker . After reading forum looks like when we connect all the speakers 5.2.2 , output power will go down from 90w to x and kilplsch RP 8000f require minimum 120w Rxv 683 : Rated Output Power (20Hz-20kHz, 2ch driven). 90 W (8 ohms, 0.06% THD) From Klipsch articles RP-8000F requires an AV receiver with a bare minimum of 120W per channel (8 ohms), and no more than 300W per channel (8 ohms). Thanks in advance
