Amp for Coincident Super Eclipse

I recently bought a pair of these speakers used, and in the process of a move, my amp has disappeared..

So I'm looking for a replacement - I'm using a Joule Electra preamp, and am considering a Moscode 401HR, 300B monos, or even a Threshold T-400 (overkill perhaps but I like the idea of power in reserve).

Any experience or thoughts on the best pairing(s)?
