semi-budget sys - under 1450

Apologies if you've seen this on audiorevew.com...

Speakers I'm down to:
B&W 602S3s or Paradigm Studio 20s or 40s
Integrateds:
NAD C370 (sounds worse, but hey, it's 105 watts)
Rotel RA1060 (what I thought I wanted until some damn aimable salesman my age played my wife and I the
Arcam A75 (which is my current fav but a stretch for my wallet - only 50 watts, but lordy what soundstaging - it's uncanny)

play mostly rock, nice nice soundtrack) and left-field electronica (no boom-boom-boom-boom, thanks) and just enough jazz to make me listen close to cymbals and timbre while demoing.

if i get the paradigm studio 20s and arcam a75 for purity, i would have to add a subwoofer at some point. if i get the B&Ws and anything else, I'm gonna wanna bi-amp (unless it's the NAD, in which case I would probably just sell/trade-in it) I think. what would you do? throw more speakers at me if you want but let's try to control my urges to build a $2000 core system instead of a $1400-1500 dollar one. thanks everyone!
