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.

@jafant,the addition of a SS2 with an Integrator has been an amazing journey. They totally transformed the speakers (2.4's) by crossing them at 50Hz. The mid range opened up and the top end is oh so smooth and detailed. The most amazing thing is the "expansion" of the space, not only left to right (which was awesome already), but up/down and back/forth. The subwoofer taking over the low end added so much space to the recordings and makes it super easy to pinpoint location of sounds.
@btg88, it's not absolutely necessary, specially with the 2.7's, 2.4's or the 2.3's, but it sure doesn't hurt. I would first make sure you have an amp that can deliver lots of current and is stable down to 2ohms... the 2.4's dip pretty low and it's not an easy load for an amp.

You can easily spend MUCH more on the front and and the amp then on the speakers and the Thiel's will still not be the limiting factor.
audiojan, the amps I am considering are the Bel Canto 600 Ref monos, Parasound JC1 monos, Pass Labs 150 INT, Benchmark AHB2 run in mono. I'm strictly a non-streaming digital guy, so front end will be PS Audio DAC and Transport.
So on a whim I listened to a pair of Audio Physic Avanti 3 (not really a whim as my buddy has a pair of AP Virgo 2's) and the Thiel CS2.4's are now moved into storage. The AP does everything as well as the Thiels, but are smoother (without losing details) and I have never experienced speakers that can simply "disappear" like the AP's can. I'm VERY happy with them.

It's a shame to keep the CS2.4's in storage (although it's in a finished attic, so not much of a storage per se) so I will get them up for sale. The only thing I had to give up with the AP's is that they're in Cherry, not the Maple that makes the 2.4's look so darn awesome!
