+1 on the Carbon specials. Like most of the S line they an be found for a good discount now that the new ones are out. I find them extremely musical, fast, and augment everything; soundstage, depth, physical involvement, imaging. While a line array does do other things, being that each one on the stack is independently tuned, they come at quite a cost esthetically in the room. Sub placement is everything, and it took me a while to get the standard 'just inside my main speakers' out of my stubborn preconceptions. Running them with REL's wireless system (super easy) allowed me to place them on the side walls and re-tune them, eliminating large room nodes and bounce back from just behind my listening position. They are elegant as well. I have a pair of the older Carbon Limiteds and the newer Carbon Specials (in two systems) and both are fantastic. Both pairs are positioned on the front part of the side walls, and not only integrate better, but get out of the way esthetically. Once adjusted, I never need to even look at the rear controls.
