I've recently acquired two pairs of Signature S1s (v2 & v3). I'd like to get a C1 to go along with them, however upon further research it looks like those rarely make an appearance on the used market. Reluctantly, I could go for a C3 also, but looks like the same issue. And at $2700 new, along with a 120-mile round trip through gut-wrenching traffic to get to the closest dealer - well, I'd rather not.
I've read that the Studio 490 & 590 could be a good match, however they have rear ports and I'd be concerned that eventually this center may wind up inside a TV stand's center slot. Maybe I could plug the port(s)?
So, besides the usual online sale sources (audiogon, usaudiomart, here, etc.) what are my best options to find something that meshes? Obviously, a matching shape to the S1 would be preferred (IOW, no square boxes).
