Can a Pass Labs XA160.5 Drive a Set Of Thiel CS7.2

I have a pass Labs X600 which is being used to drive a set of Thiel CS7.2's. I'm considering upgrading my amp to either a Pass Labs X600.5 or a Pass Labs XA160.5. Everyone seem to love the XA160.5's. However, I'm concerned that the XA1605.5's won't have enough current to drive the big Thiels. I've had Threshold T400's and Pass Labs X350 paired with the Thiels in the past and I was unsatisfied with the dynamics.
