The Maggies are great speakers. Not all that dynamic, but so clear, so nuanced. I had 20.1's. It's true that you need them about 5' out into the room, that you may need something on the front wall to deal with the rear wave, and that they tend to need alot of power so you have to factor that into your budget (a powerful amplifier). They can go closer to the side walls. Quads will have similar acoustic considerations but require less amplification. They are less dynamic than the Maggies, but even clearer in the midrange and can really dissappear. So many choices - but you are looking at good stuff!
