Lamm M1.2 v. ML2.1

Has anyone had the opportunity to compare the Lamm M1.2 hybrid and the ML2.1 SET amps? I am very curious as to how close they sound to each other and how much "magic" one might give up in going with the hybrid as opposed to the SET. I am also interested in how the L2 hybrid and LL2.1 all tube preamps compare. Thanks.
