Been trying to piece system together for awhile. So far have Athen as f1s for mains , Athena as c1 as center. Picked up a bic 1015 sub cheap on ebay. Now I'm wanting the Athena as r1 for sides and rear center but price is $125 each. Been watching the Fluance av-bp2 rears on ebay. Could probably buy 3 for nearly same money as one of the athenas. Using my Onkyo 600 will I be hearing that much better quality over the cheaper Fluances. Thanks for any recommendations!
