My mistake, sorry...H2A(I heard) or H20 have similar specs and should be powerful enough in your system. On the other hand, H10 limited edition(I heard)or H4A seem to have similar specs and are powerful enough to drive a pair of KEF Reference 207/2!!!
About sonic signature, both Hegel amps can help when you expect more speed and control, a little more transparency but not brightness, more energy(like Densen amps) and less colorations of its own. More succesful match, for example, for H2A includes Aesthetix Janus(pre) and KEF Ref 205/2 with which the system was more "energetic", "lively", with more "extended" highs and lows, tonally well-balanced. But I would not use Hegel to drive ceramic cones...
Please see H10 pic in my virtual system;)
Good luck
