Lots of good responses already, but to throw out another angle, I found that the slightly older Thiel designs were a tad warmer and more musical than their very latest designs (which seem to be more concise, yet somewhat thinner). The CS3.6, CS5 and CS7 seemed to me like they were on the warmer (yet still accurate) side of the Thiel line.
But then again, I have not heard the Vandersteen 5's...
