Amps For Revel F52?


I've just ordered a set of Revel F52's, and am looking at amplificarion options. What do people think of Parasound A51 v. Bryston 4B v. Anthem P2? Would something like a Krell 250 used be a better choice? Are there other choices in the same ballpark that would be a better choice?

I use the F52s with a Mccormack DNA-1, and it does well, although I am under the impression that more quality power will only enhance.
