I've only breifly auditioned the F32. I think they have a similar midrange; not sure on the tweeter (the F32 may be just a bit smoother, but again, similar); the biggest difference to me in the bass. The F30 seems to go deeper and with more authority based on my limited audition of the F32. The F32 has been reported to be slightly more refined, but from my limited auition I couldn't confirm that. Both sound great, and pretty similar overall. The F32 has more conventional looks that a lot of people like (same with the new Ultima2's; while not conventional, they come closer than the old models).
