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.
Cornwall and CS2.3 owner, apples and salmon comparison.....but first, get moved into your condo and listen to what you have BEFORE upgrading into what ????
also, I would be very inclined to buy Jim Smiths book - Get Better Sound, that will help you get the most out of anything you buy in your room.
enjoy the music !!!!!
Having lived with the 2.2s for a long time I have to say that they aren't remotely bright.  I'm not an Atkinson hater at all but he doesn't know how to measure Thiels.  The first-order crossovers make them harder to measure.  There may be some Thiel models that are on the bright side but the 2.2s are not among them.  At $800 the 2.2s are an obscene bargain.
I've been running Thiel 2 2's (no decimal point...) for 25 years without the slightest urge to "upgrade." Whenever I hear other speakers that I think sound "really good," I come back to the Thiels and realize they they're as good or better.

That said, some things to note. As other have observed, the Thiels DO require a top quality high-current amp that can drive their low impedance. I drive them with a Classé CA-200 (Kimber cables). It's a match made in audio heaven. Also, my listening room is relatively small and very well damped. I use a now classic actively crossed over Mirage sub with them, and the result is a system that is essentially flat, and coherent, from 20Hz on up (Thiels by themselves roll off in the low 40's). Positioning is important, too. Away from walls, NOT toed in and in an equilateral triangle with the listening position. They're not too bright at all, but it's all there, and they're a joy to listen to.

So it depends. YMMV. In the wrong room with the wrong amp, there'll be no satisfaction. But, heck, @ $800? A screaming bargain. Spend your savings on a good amp.
25 years with the same speaker?  That's remarkable.  What are you even doing on a site like this?  ;-)
@prof. "What are you even doing on a site like this?" Not much, actually. I get Audiogon's e-mails. I'll sometimes notice a topic of interest and will occasionally toss in my 2¢. Thiel 2 2s are of interest. Balanced AC and active monitors are others.
