Coolness,
Have heard a lot of good regarding most KEF models reviews.

Is the room his KEFs are in much smaller than yours? Maybe to small for similar sound stage?
With all Axiom speakers being reference grade, not overly surprising that your M100s would give more detailed separation of tracks.
With my M80s and a bad recording it's almost like a really lazy Les Paul went and layered tracks together and you can separate them so easily they don't even sound layered anymore.
