Should I buy used Thiel CS5

 If they are in good condition, a definite yes, as even by today’s standards one of the greats, but only if driven from an amp that is stable and can deliver big current into 2ohm continuously and remain comfortable doing it.
Stay away from tubes, most Mosfets, and Class-D "if" you want to get the very best out of them, read here.

The price seems high to me . For comparison , I bought a pair of CS7 off craigslist with a matching center channel and a pair of cs2 for $1700 
You should ask this question on the Thiel owners posts which has been running for a few years and seems to get daily activity too .
