Thiel CS 2.2 Speakers... What you all think?

So I'm putting together a system and there are some  Thiel CS 2.2 speakers in mint condition for $800 in my area. What do you all think of the speakers and the price? I really appreciate the feedback and any considerations I may have for them. I have an Outlaw 5 channel amp and a Marantz pre-amp. Currently running some Klipsch Heresy II speakers. 

Would these be a great upgrade? TY to the community for helping me.
I owned Theil 2.2's back in the 90's.
I went through quite a few speakers, including Maggies, Alon's, and Dynaudio.
The Theil's were my favorite and after I got them I had no urge to upgrade. Owned them for 15 years.
At the time they were 2,800.00 and worth every penny.

The Theil sound fit my taste for outstanding detail and imaging. 
I drove them with a Conrad Johnson Premier, 7a at 70 tube watts per side.
They are capable of prodigious bass. The Connie J wasn't able to bring that aspect out, but the mids were glorious!
That was 20 some odd years ago. These days solid state amps have improved, so I would recommend a high current solid state amp. 
If clear mid range, crisp treble and outstanding imaging are what you value in a speaker you will nor be disappointed with the 2.2's
Oh, the build quality and finishing are first rate.
I had 3.6's....a fan of Thiel.  Too bad it went away.   Thiel is a transparant speaker...  If you have good components, it will reward, but will also reveal warts.
Welcome! Are you currently out of our hobby? If so, would love to see your return to Thiel Audio loudspeakers.  Happy Listening!
Hi Jfant & all,
Thanks for the welcome.
I have always been into mid /  higher end audio.
We've moved a few times in the past few years, So gradually have been downsizing.
 We're moving to N.C. next month, so I recently sold off my system consisting of Rogue Audio Sphinx amp, and Totem Rainmaker speakers. My source for the last few years has been high rez. computer audio files. At one time i owned around 3000 vinyl albums (VPI HW19 Mk. IV, Morch 7 arm, Benz Micro Grasshopper cartridge) and several hundred CD's. (Esoteric Audio transport and DA converter),
That's when I had the Thiel's and C.J. along with Convergent Audio Pre amp. I got out of the hobby for a few years and sold that stuff. 
I just recently got into headphones (Grado GS1000, Focal Utopia, Quad ERA 1, Linear Tube Audio Micro Zotl amp, Audo-GD DAC, Synergistic Research cables). 
So a thumbnail sketch of my audio history.
After we settle in N.C. I'll probably be looking for a speaker based system again. Thanks for the welcome.
