Reasonable integrated amp for Magico A3

Hi guys,
I have just ordered for a Magico A3 and am waiting for arrival. I do have Naim Unity Nova and I think this might be good enough. I am trying to find out from forum here, who have (or even if they don't have), A3s, what integrated amps are being used and recommend. If Nova is not enough, I might considering switching to other integrated. Considering Esoteric F-05 or Pass labs 250 or Vitus R-101.
