Van Alstine SS vs. McCormack DNA amps

Hi, I'm looking to upgrade to separates to power a a relatively new pair of Salk Songtowers. For the amp, I'm focused on the Van Alstine Insight line or the McCormack DNA 125. Hardly any reviews of the former, and lots of glowing reviews of the McCormack. I'd appreciate any feedback from anyone who has heard both, or at least compared something in the McCormack DNA line with other Van Alstine solid-state amps.

Thanks.
