upgrading from Spica TC60's to ??

I have had the TC60's for a long time, and the TC50's before that. I feel I need to upgrade under the assumption there have been some advancements over the last ten years. Other than that I love my speakers. My electronics are pretty good including a CJ 11A, 70watt amp. I have a small room and am considering a small/medium floor standing speaker. I would like to hear from someone who had these speakers and found something better, not just different.
