Had the S2 now a few weeks (purchased at the LBGS) and I love the thing, A local, well respected, producer/engineer described the neck as 'playing glass', a good analogy I thought. I believe the mid range frequency sweep is wider on the B2 but has the same cut/flat/boost switch. I would suggest, give Status a ring, and if possible, go visit Dawn, Rob and the guys at the 'factory' in Colchester. They had a B2 at the show which may still be available. If not it's a couple of months wait, well worth the investment IMHO. Go for it.
