Aragon 4004 vs. McCormack DNA-1?

I am looking at a new ( to me) SS for my system. I am using a pair of Vandersteen 2ce Signature speakers and a Sonic Frontiers SFL-1 Signature preamp.

I have tentatively narrowed it down to a stock DNa-1 and a stock 4004.

Anyone care to offer experience or opinions on those two choices? Cost will be close to the same although the McCormack will probably be maybe $100 more.

From what I have read both are pretty good amps with the Vandys and I like the fact that McCormack is still supported by the designer.
