Magnum Dynalab 308 drive Magnepan 1.7 or 3.6?

I drive MG 1.7s with a Musical Concepts modded Hafler DH-200 in a room thats about 25x 24... 100 watts per channel into 8 ohms. About the only thing that taxes that amount of power so far is the Telarc SACD of the 1812 overture with cannons.

mine took 90 days last year. Once you get them, take some warhorse pieces like "night on bald mountain" or like that uses full orchestra loudly,set on repeat, turn amp to preferred volume, exit the room, and come back in 10 hours... they are basically stiff when new and need to flex to gain full transparency. 10 hrs won't be enough for full break in but it should allow you not to fret at the first serious listen. Takes about 100 hours to reach full potential and sounds a bit edgy in the highs during initial break in... this goes away unless the edge is really there from the equipment/cables feeding.
