Martin Logan Summits/Cary 805's, does this work?

I recently bought a new pair of Martin Logan Summits; I had planned on moving to a pair of Cary 805's as the rated efficiency is 92db. However the owners manual reccommends amps of at least 100 watts per side. I am currently using a pair of big tube amps, so no problem.
Has anyone tried or experienced this combo? Comments?
By the way, so far I am very happy with these speakers (10 hours of play to this point.)
