The OP is currently using powered speakers with 20 wpc internal amp. The Lux is 30wpc into 8 ohms, 40wpc into 4 ohms so figure 35wpc into 6 ohm speakers. And this is RMS watts, actual peak power will likely be closer to 50 or even 60wpc. He'll have plenty enough power, whatever he decides to get. It's the first watt that is most important, and Luxman is good clean power.
OnTheFritz: Take ALL speaker recommendations with a grain of salt. Or two. Just because a pair sounds good to me in my room doesn't necessarily mean that you will like the sound in your room. And yes, the ELACs are a little expensive. But they were designed to be music speakers first. According to A. Jones, if a set of speakers can do music well, they will do home theater well also. The reverse is not always true. Don't get me wrong, the Polks that were recommended are also pretty decent little speakers. In fact, my main music speakers are Polk Monitor70's, large floor-standers, which replaced a set of Andrew Jones-designed Pioneers, so it's not like I'm prejudiced. The point being, get what YOU like, and don't worry about what I think...
(Edited to add: The main reason the Polks replaced the Pioneers in my front room is because I run separates, and have no tone controls. I decided that I needed more bass in my rather open listening space. My options were somewhat limited, but I chose larger, more efficient speakers. And, had the ELAC F6 been available at the time, I would likely have gone with them)
