Thiel CS2.4 to what?

I'm getting the itch to upgrade my speakers (Thiel CS2.4). Nothing really wrong with them, they image like crazy, is like a clear window into the music, but I sometimes feel they are a bit too "reserved" and missing the joie de vivre. Looking for something that instills more life.

Rest of the system is PS Audio DirectStream Dac driving a pair of Bel Canto Ref500M. Front end includes a PS Audio PerfectStream Transport, a Auralic Aries streamer, Clearaudio turntable with PS Audio NuWave phono. All cables are Cardas.

My room is a semi-dedicated room (sharing it with my office, which is in an alcove off the listening room). I do have a sloped ceiling on the front wall (it's a finished attic), about 16' wide and 14' deep. Some acoustic panels to tame reflections.

Budget would be in the range of $4-6000 above what I can get for the Thiels (thinking about $2k as they are in awesome condition and has the upgraded maple finish). Basically, what would you recommend that is similar to the Thiel, but has more dynamics and a bit less sterile.
