Speaking for myself, i have tended to enjoy Thiels with high-current, powerful amps. I have heard them Krell KAS-2s i think, as well as Forte 4s (the Class A 50-watters)...that has been the way i have enjoyed Thiels...some of their best characteristics seemed to me to thrive on the current, open up, free up and really become more lyrical while maintain all the discipline and control Thiels were designed for.
