Martin Logan - wow

I heard my first electrostatic speakers yesterday, ML Ascent at a very helpful dealer. These are clearly my cup of tea -- I liked better than the B&W N802s I listened to at the same time. Vocals are amazingly present. So of course I have some questions:

1. The bass wasn't great. Better than a monitor (I listened to B&W N805) but not much punch, and more important, sounded a little sloppy. Are there adjustments that one makes to the crossover, some little magic knob, that might improve this?

2. Are most users combining with a sub for stereo use (I'm not doing HT)?

3. We listened in a small room (about 8x8) at the store. My room is about 25 x 14 x 8', with speakers along the 14' wall. What model of Martin Logan would do the best job in this room? Bigger, smaller? I mostly listen at low-ish volumes, but would like to crank it ocassionally?

4. My amp is a Classe CA-200 (the newer style, same as current CA-201). Will this amp do justice to the speakers?

5. Other speakers I should listen to? I hear "maggies" and "innersound" -- are there others to consider?

Thank you!
