I currently have a pair of floorstanding Pioneer FS51's and I'm wanting to upgrade to something a little bit better. I've found a pair of Aperion Intimus 4T towers as well as a matching center channel on the used market that I'm thinking about getting. Their asking price is $475 but they may have wiggle room. Has anyone heard both of these speakers? How would they compare for two channel music listening? Would it be a significant upgrade that is worth the cost or should I wait and try to spend a bit more for a legitimate, hands down upgrade? The towers seem to have good reviews online. In case it matters, I will also eventually add a subwoofer to the mix, which will probably be an SVS SB-1000 or 2000. Thanks guys!
