Would Dynaudio Contours mate well with Denon?

I hear that the Dyns. need a lot of clean power. I would like to know if anyone has had any experience with the Contour line mated with a Denon 5700 reciever. and if so, how well (or poor) it sounds. The Denon has 140 w.p.c., but is a reciever never the less. I'm looking for a great all around (5) speaker set for this unit.
(70% music , 30% h.t.). I have not heard the Audience line yet,- don't care for B&W much. Please give me your sugestions and opinions.
Thanks.
