Recommendations for replacing B&W 804s / HTM3s

I've gotten the itch again and am toying with the idea of replacing my trust pair of B&W 804s and their voice matched HTM3s center.  I use a Classe Sigma SSP processor feeding a Classe CAV-500 amp, so there's plenty of power.  My uses are 95% home theater, and there's a JL Fathom sub rounding things out.  My condition is that whatever mains I go with *must* have a matching center, so that narrows the selections significantly.  Any recommendations that would be $10-15k total on the used market?  Thanks!
