Having owned the SCM 11 and 19 as well as PMC DB1i (with Bryston gear), I second the PMC vote. The ATCs are great speakers but they lack bass due to the sealed cabinet. Very accurate revealing speakers, but the PMCs are also very revealing but much more fun and to me have a more "live" sound. The TB2i is excellent.
I'm also very fond of Dynaudio. The new Focus 160 is getting great press. Worth checking out as well.
