I forgot to mention that, until the m-500 arrives the juice powering these Klipsch's is the TEAC AI-101DA, a 26w/ch. desktop amp/DAC. I love this tiny unit. It will power any of my speakers, including the KEF C-40s, B&W 601se's and others, but with the 96db Klipsch's it really shines. I won't be giving it away to anyone, unlike the Denon receiver I never got around to plugging in. Still sitting here on this desktop, unused. I planned on using it and doing a 5.1 setup, but I find that I prefer 2.1 and the TEAC has been more than enough for near-field, plus it's hi-res capable.
