Electrostaticman: You can't offend anyone by asking, and I think your question(s) are quite specific enough. And some of us may not have seen your previous post, so don't be embarassed.
You can check out my system for ideas. As for tube amps, I still think they're the best idea with stats, especially if you're not driving bass as with the Summits. I used to use a pair of Trioded ARC M300 Mk2's (140W/ch) with my CLS's and they were great! But I don't have room for them now. And even though they were circa 1989, they had 2 ohm speaker taps! Although I found the 4 ohms gave me the best response across the spectrum.
I have also found after much experimentation, that using the largest AWG power cable (9 or 10) makes a very audible difference with all ML stats -- though I can't figure out why, because they really don't draw much power
