Art Audio Carissa? PX-25? Druids?

I've been curious about Art Audio amps for some time now, and finally decided to try something of theirs with my Druids. The trouble, I guess, is that there are two models within my price range---the Carissa and the PX-25---and the reviews on both have been a curious read.

For example, 6moons says that Carissa is quite aggressive and has superb body (my cup of tea) with a 95dbW/m speaker, but is "humid, slow, and deliberate" with the efficient Duos (not what I'm looking for). positive-feedback goes the other way and calls Carissa "light, airy, and expansive" (not what I'm looking for either). Same kind of deal goes for PX-25---called forward by some, called laidback by others, etc.

Since there's not a chance to hear either amp in my system before buying, I'd like to see if anyone has heard either or both of these amps with Zu speakers. Which has a better chance of being a good match? Any comments'd be appreciated.
