As a Magnepan owner I understand anything I say will sound biased BUT at one time I was considering both. To me, the difference was between a great "in theory" design compared to a "less perfect" theory but better execution situation.
A planar speaker fused to a very dynamic woofer seemed like a great idea. It should provide the lower octave that the planars, including the Maggies, were missing. However the Martin Logans, while sounding very clean and open upon initial listening, started to bother me after 15 minutes or so. There was a noticeable difference between the speed of the electrostatic driver and the much-too-slow woofer.
It just didn't work for me... and I went in WANTING it to. (I loved the look of he M-L's and thought the closer to "full-range" speaker would be perfect.)
The Magnepan 3.7, to me, had a much more coherent sound, a very nice three-dimensionality and better ability to locate instruments in space. They also just sounded more like real music, especially on vocals and acoustic music.
Just one man's opinion.
