Center channel to match Linn Index

Looking for a center channel speaker to match up to Linn Indexes. It will get limited use in a second system. Of course, I have posted and will look for Linns, but any thoughts on other speakers that might be a good match. Remember, this is not for a high end HT, actually only have an SD Panny CRT for display. System is in a second home so do not have unlimited access to swap in and out for testing.
I've heard people compare the second generation Ascend Acoustics 340 to Linn's sonic signature. It's a shot in the dark and you'd be out $40-50 in shipping if it didn't work. I haven't heard either speaker.
