I use a pair of bridged Classe DR3 VHC monos in one of my systems and feel that they still hold up very well to current amps. I'd be inclined to stick with them if I were you - any improvement might be infinitesimal but at a far from infinitesimal cost.
I ran the Classes in my main system for awhile, driving Wilson Maxx 2s but found that I like a CJ Premier 11a just a tad better.
