thanks for all the info guys!!
I actually made the jump and purchased all the mains, center and surround.
Unfortunately I couldn't break the bank for def tech

but I got a killer deal on these models)
I ended up getting Boston acoustics E100 mains, E70 center and E40 for the surrounds. So now its time to search for a woofer and receiver.
QUESTION:
front L/R are rated at 400Watts, would a receiver with the output of 130W do it justice? If not, should I get a power amp to run them?
I am now looking for a woofer and want to spend $6-900. I have searched and I guess everyone loves the SVS SB-12. Are there many online retailers..or am I limited on ordering directly off their site?
Should I get a power conditioner?
THanks!!
