I know its a bit of a deviation from your system but I'm currently using Magnepan 1.7's with a Velodyne DD-12 (second sub is on the way). I'm super satisfied with the setup and rock music is the bulk of my listening.
Adding a pair of subs would be your best route, IMO. You'd have to give up a lot of resolution to get a different speaker altogether with more thump. Maggies w/ sub is a minimal compromise solution.
