igmaty,
Congrats to your seat at the table. That speaker is a steal on the used market .
My advice would be not to use your current amplification as they will add too much distortion and most likely clip and possibly lose a driver, or two.
Amps worth considering that are within a 2-3k price point are the lower wattage Krell FPB, Pass Labs, Threshold, Classe, Mark Levinson.
I would pass on Bryston as my experience has been they do not mate well together, especially after hearing the list mentioned above.
I’m no expert on this matter but I have owed/own a few Thiel’s and have tried a good bit of the high current amps out there.
Without the right amp the Thiel’s will never move you the way they were intended.
