Actually, looking at the Hegel specs, that amp may well be able to drive the WATTs (it seems to be rated into two ohms, albeit at 60 watts into that load). A little more than the OP wanted to spend though, even used. Audiotroy used to be, or may still be, a Hegel dealer, he might be able to chime in.
I'd still question the WATTs as the best choice for a home theater, though, given the lack of bass. The WATTs also need stands, are finicky in setup and work best out in a room away from walls, don't know if that's going to be a problem for the OP.
