Hello,
if you're in the UK, i think the price of Kef reference 207/2 is very competitive.
i don't know bw 802 (only heard 804 i don't like at all) but if you don't like the bw 802 maybe you'll like the kef.
If you want big, powerful, low extension bass, kef is not for you.
kef reference 207 sound a little dull (not sure of the word, please excuse my english, i mean not "clear" or bright)
they provide many informations (depends on source materials of course), when i heard them the first time i thought we've changed the cd player.
also no problem of delicate sweet point like many speakers.
For me, they made the difference on classical music, not on pop/rock.
I was not convinced by other kef reference models (203, 205).
I only wish kef 207 were smaller.
I can also advise rockport mira speakers but never heard with nuforce.
my full system is arcam fmj 139 + jeff rowland capri + nuforce se V2 + kef reference 207/2.
good search.
