I have a Denon AVR-6400H receiver which I thought was good enough to push my Klipsch f\/r\/c. I found because the basement is large with carpet and approximately 16x24 feet in space I need to go really high on the volume to get good sound. The Klipsch I believe are easy to push so I'm wondering if a 3 channel Monolith or Emotiva Amp would be better to push the l\/r\/c? The Denon is "rated" at 140w per channel at 8 ohms. I'm guessing that number is inflated. Thoughts on the amp to increase the sound?
