I have 3.6's, different speakers but same family...I've used Classe CA 200...good, and now using Mcintosh 501 mono's ...outstanding. My 2 cents. good luck with your choice, there are alot of good ones.
I probably took to long to answer this thread, but I have been very happy usuing the Bryston 3B-SST. It has enough power for powerful transients, I have been able to reach high volumes around 105 dB with ease, and louder. I believe my preamp makes everything sound somewhat "electronic" not as natural as normal. Overall I am very happy using the Bryston.
I have the 2.3, a slightly harder load, and I have used the Bryston 4B-ST, Plinius SA-102 and now the Rogue Zeus.
I've found that while power is key, the quality of power -- and everything else down the line -- is crucial.
I've had good luck over the years using Cardas Neutral Reference speaker cables.
Good luck with your Thiels. They are a great speaker. I have replaced just about every other component in my system but kept the Thiels. They really reward you.
