Which amp for Vandersteen 3As?

I am in the process of picking up a very nice pair of Vandersteen 3As. I own several SS amps and am torn between which would be the best match for the Vandys. The amps are: McCormack DNA-125, PS Audio HCA-2, B&K 125.2, B&K 200.7, Adcom GFA-555ii, and a Pioneer Spec-4. The pre-amp will be a Cary SL-100. Any thoughts on which amp would offer the best synergy would be appreciated, especially from current/past Vandersteen owners.
