Audio Note P Zero vs. Quicksilver Mid Monos

Hi there,
I am choosing between Quicksilver Mid Monos and Audio Note P Zero - both monoblocks. I have some experience with KT 77 Gold Lion tubes of the Quicksilvers, but no idea about the ECL82 tubes of the AN's. Does anyone have ever heard ECL based amp? Let me specify that both amps are in the same price range (second hand) and I have no power problem (small listening room, both amps are able to drive my speakers).
