The Klipsch has 300 continuous and 650 dynamic. I would have thought this would blast, or blow the stck sony speakers. The ad for Sony says it's a 3ohm, so I'm guessing 2 6 ohm speakers? After putting the Klipsch amp into the Sony, I tried it and was very disapointed. Then I tried to make adjustments to my Denon, and still the same thing. There was nothing wrong with the Sony amp...I just wanted more!
