I haven't heard the Epos but they have a good rep. Our Denon dealers mostly carry B&W, the combo of Denon with the entry B&W sounds pretty good.

Are you set on biamping for some reason?

Don't get caught up on specs. It's a good thing to have more power than you need and will not hurt anything as long as you don't go too far with the volume. In most instances a speaker is fine as long as it receives clean power. It's when you try to drive a speaker loud with out enough power that you run into problems. This causes your amp to "clip", the signal from the amp becomes distorted and this tends to blow speakers, especially tweeters.

If they would be in your budget, take a listen to Dynaudio's Excite series.
