Hey, my name is Mark and I'm having trouble buying my first surround system. I'm thinking of a 5.1 setup at first, but might one day upgrade to 7.2. The speakers that are currently in my consideration are the Klipsch RP-8000f and Klipsch RP-504c, I might pair that up with a BIC America F12 and an RP-500m to complete my setup. Does anyone have any suggestions? I'm not that new to speakers, I understand connections and setups at a decent level. Where I'm struggling is what receiver to buy. At first I was considering the Yamaha RX-V683BL, but I later learned that this would be too weak to drive my setup. Now I know I need to spend over a grand on the receiver unit alone. With that said, any suggestions for a receiver? I apparently need close to 150 watts per channel to drive these speakers adequately, is that true?
