I just bought a use pair of loud speaker rating 30-400 Watt. I want to use it conjunction with my Bose (5 speakers) home theater system. I asked a guy from Circuit City, he sugested to use the receive HK avr525. I look at the specs of that receiver, it only have 70W/ch. I don't think I'll get all the juice out of my speaker. Do you think I should use a power amp to connect the loud speaker and the Bose for sur sound? What power amp do you suggest? I'm thinking of PYLE PRO, NUMARK, or GLI PRO. Anyone familiar with these amps?
