I have Dynaudio Contours (3.0's in front, with matching center, Audience 50's in back), so I guess by definition that's what I'd recommend since that's what I decided on. I have a dual purpose system that I avidly use for both music and movies.
I think something along the ATC suggestion is the other "path" I'd investigate (or will investigate if I ever change what I currently have. The Dyn's are nice, and are my first choice in music, but probably wouldn't be my absolute first choice in HT. Something that's a little "quicker", which will probably come from a more monitor-like speaker, and quite possibly is self powered, at least in the bass, would probably be what I'd pursue for a system that was more HT, but where I wanted good music as well. Other brands I'd consider along these lines would be Infinity, M&K and NHT, to name a few.
Finally, Martin Logan would be an excellent choice, particularly if you listen to music where electrostats excel. A pair of Odyssey's up front would be an excellent start, and they make dynamite center and surrounds to add later.
Certainly the Dynaudios and the ML's would require (at least ultimately) an upgraded amp for the fronts to fully realize their potential. They both really like their juice.
