Sound Lab vs Magnepan 20.7

Essentialaudio - With all due respect if I may correct you, electrostatic speaker panels do not have any magnetic coating. They are a non-magnetic design, and the membranes need to have an electrically conductive coating in order to be charged to a fixed positive voltage. The rest of your explanation of their operation is correct.

While the Legacy Aerius are fine loudspeakers, I do not find them to be at all comparable to Sound Labs or Maggies. The Aerius are fine box speakers, but do not 'float the sound in air' the way that a fine panel speaker does. I also do not find them to be as seamless or transparent. I prefer the true ribbon Maggies, either the 3.7 or 20.7 to the SLs, but that is strictly a matter of taste and space. The really large SLs are awesome, but they are just too large for most normal size non-dedicated listening rooms. I also prefer the high end of the Magenpan true ribbon, as the finest reproducer of its kind I have ever experienced. Of course, YMMV applies!
