thanks for that,i own 601s(602s on the list) i had my 601s passive bi-amped.the new arrangement did not allow this,but have since acquired 12/4 wire and will bi-amp again.i'm only dealing with 60x6 B&K amp,so it's not like i have gobs of power (the 1050 takes care of center/surround)

i noticed a huge difference in sound and stage,but will not get into that.

btw i use n805 jumpers instead of those cheesy straps when doing 'conventional' wiring.
