Thiel CS3.6 and GCA-250 Any Opinions

Hi all.
Looking at picking up one of these amps, just wondering if anyone has heard this combo?
I do not see the current rating on the amp, just power ratings.
Just not sure if it has the grunt for the big Thiel's.
Used to own a HCA-2 and I liked it, and the GCA is supposed to be better.
