how much more would a PW-2200 be over a PS-1200..
I started out with a 1200 a loved it.. Sold it after a while then started the hunt for a sub... I probably had about 7 sub I was able to take from from B&Ws, Every Boston and a SERVO-15, PW-2200.. and the new V2 or V3 PS-1200 I ended up keeping the 2200.
It sounds much better then the 1200 in every way. I think its only a couple hundred more... The 1200 sounded ok on its own.. but beside the 2200 it just went home..
also see if you can but a nice deposit down and bring both the B&W and Paradigm mains home... or maybe just one of each... or if only one store allows you to bring them home for a test... Bring them to the other store

You dont know until you ask.. I had my Boston 965's beside a pair of B&W 603s and a Anthem amp... (none were mine

) and again I ended up keeping the Bostons as the B&Ws sounded so bad beside them.
Oh and I would personally go with the Paradigms
Actually I Just checked Paradigms site and it looks like they have a new PW sub.. the PW-2100 It looks like the only diff from the 2100 and the 2200 is its a 10inch not a 12 ( but same 400W wamp).... I just keep finding more and mroe.. check out the Seismic™ 12 lol...
