hey, i went into bestbuy today thinking to audition a pair of klipsch bookshelfs thinking i would buy a new pair of speakers for myself. turns out managers special was out, bought a pair of rf 82's for 187 each, and pair of rb 51's for 125 for the pair, and a klipsch rc-62 for 125. amazing deal, i couldnt leave it. tommoro im going back to buy out the rest of there stock of the managers specials. but geting to my issue, i have an onkyo sr605 reciever, will that be enough for the speakers or will i HAVE to buy a new reciever to enjoy them? and if so which do u recommend for the best bang for the buck?
