Yes, I have ML2s with my Duo Omegas. Best combo I've heard with these speakers (formerly had Cary 300SE, and have heard Audipoax 88 with Duos as well).
The ML2s really shine in the bass with the Duos, and they have an uncanny ability to "get out of the way" of the music - temporal accuracy, PRaT, whatever you want to call it...propulsive.
Vladimir Lamm told me that he also considers this an excellent match.
