DNA-1 and Vandersteen Quatros

I'm looking at a pair of Quatros and have an unmodded McCormack DNA-1 that I'd like to continue using, at least for a while.

I've heard that McCormack amps work well for other Vandys but has anyone tried this particular combination of DNA-1 and Quatros? Any issues with input impedance and the high pass filters that the Vandersteens require?

Thanks in advance.
