I own a Creek Evo amp, and have owned the Evo CDP and the Epos M12.2 as well.
The sound is lean, fast and a bit harsh when pushed too hard. But at reasonable volume the sound is very sweet and musical. With rhythmic music (pop, jazz, some rock) they shine. Some classical music works fine too.
If you like the PRaT thing you will love them. Epos speakers have a very particular sound. I think either you love them or hate them. Me, I both love them and hate them! 
"The problem with most modern speakers is that they create their own space —a phony sense of air— and then put the music into it. On the other hand, drivers like the Hartleys put the music into the same space as the listener."
