Hey all, I'm a relative HT newbie so forgive me if this is a "dumb question". I recently bought a Sony rerceiver to power my Klipsch Reference series 5.1 system. The receiver is rated at 110 watts per channel. In browsing this forum and its links I've come across many separate amps costing a lot of money and yet only delivering say 50 watts (tube amps). Now I'm confused. Do my speakers really only need/get a fraction of the receiver's rated watts/channel? What is that fraction? What does the watts/channel rating really mean. How do I know how much power my speakers need to sound best? I'm just looking to better understand my system. Thanks for any comments.
