Dynaudio Contour vs. Confidence

Does anyone have any experience comparing these two lines from Dynaudio? I currently have the Contour 3.0's in a medium sized room (13x18). I love the Dynaudio sound, and am curious as to what the Confidence series brings to the table. The Contours are well reviewed, but the Confidence line hasn't seemed to received a review anywhere that I can find.

I'm also curious as to the differences in performance between the Confidence 3 and the Confidence 5. Would the 3 work better in my room size? Would the 5 have an over-powering amount of bass? How much diffence in amplification would one want to have? I'm not too keen on getting a high-powered amp that heats the whole room.

Basically, I'd appreciate any comments, comparison or otherwise. -Kirk
