And here is a quote I found from a different forum...( In reference to the RF-7, RC-7 etc.. home theatre set-up with a pioneer elite receiver)
"The speakers you have right now are very efficent. I can not imagine you are taxing the capabilities of your current receiver as it takes proably no more than 5 to 10 watts to drive your Klipsch(s). So an external amp would add nothing that you do not already have. I can certainly understand if it is a case of upgradeitis and having a new toy if that is what you are going through, but any change in sound would be the dreaded placebo effect."
I am in the market to add a power amp to my set-up. Somebody, please tell me this post is not accurate.
