Anyone have an opinion of these? Best bang for the buck? THey are in order of price... at least what I can get them for. The B&W'S are about $1200 a pair. The kef's about $1000 and the Infinities are about $600. I love the way they all sound and I am pretty sure Im gonna do a sunfire Ultimate Reciever for any of them (200X7). Is that over kill? I think My best bang for the buck is gonna be the infinities. But I just want some opinions.
