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.

As the owner of six Thiel speakers, I will add my vote for keeping the Thiels and adding a sub.  Just make sure that you add one that 1) has lots of options as to phase and crossover frequency, and 2) is "quick and tight" to match the Thiels.  Flat to 32hz is just fine for music.
@harrylavo, I think that's exactly what I'm going to do. I listened to a few other speakers during last week (some much more expensive than the Thiel's) and I was underwhelmed, just didn't have that "window into music" quality.

The goal is to find a Thiel subwoofer (or a pair would be ideal, but I'll settle for one for now). I already have the Integrator.
Been there done that. I’ve had three pair of 2.4’s, as I always go back. Going up the line is not the answer,either. Rocky Mountain Audiofest is coming up in October, could hear a multitude of speakers there. You have a great system. Good luck!
@audiojan “window into the music” as you describe is spot on! That is one of the addicting qualities of Thiels. Also, I personally would never leave before I maximized all other compenents and cables upstream synergistically.

My Thiels have always kept up and risen to new levels of performance with every component upgrade I have made.
