Mark Levinson ML-9 or McCormack DNA-1?

I'm looking for an amp and wonder if anybody has experience with both, and can remark about their relative merits.

What speakers would you be using with the amp?
I have Snell E's (and Superzeros and Minimus 7s) but am about to buy some Sinclair Brighton 490Ts I think. These latter I've never heard of but they are at the local shop for a very great price and I've listened to them for hours and like them a lot:
I have never heard the McCormack DNA-1, but I can vouch for the Mark Levinson ML-9. It's a great find -- detailed, warm, lots of headroom and power to spare.

Good luck with your search,
