I'm unconvinced by the AN units I've heard thus far -decent enough, but they simply weren't as good as their Fostex equivalents, and once shipping etc., is brought in, they aren't really any cheaper either. So I can't really see the point.
The models that interest me are the 10in (as nobody else does one) and the cast frame units, as they at least offer something different, which is all to the good. The 12in is a nice idea in theory, but Vas is so high, I've yet to figure out what it's actually for.
