Thiel CS 3.7 owners

I'm not an owner. But I have heard them on at least a dozen occasions, most for extended listening, with various electronics.
Sonics... are slightly warmer than other thiels, but still very detailed, and balanced throughout the freq. range.
Aesthetics... I think they are beautiful. Fit and finish is first rate.
They absolutely soundstage and image like champions. If they come out with a replacment to the 7.2, my wife is going to kill me.
Lots of threads about them here on Agon.

The CS 3.7 is a very large and killer speaker. It needs a large room to "breathe" and open up proper. 20x20, 25x25 or 30x30 will do very nicely.
Add a robust ,solid-state power amp, and you will be rewarded.
