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.
My understanding is the McCormick is 100 K input imp
this would work fine with Quatros.
Its always best to optimise and do the step listed in the Vandys owners manual with matching the x over perfectly.
Please let me know if you have any questions
Best Johnnyr
Johnnyr, thanks for the reply.

Can anyone who's using a DNA-1 to power their Quatros comment on the sound?
