I bought black cloth and aluminum trim for 2 reasons:

1. I think Maggies in light trim and cloth can look kind of old fashioned. The black and aluminum freshened up the look and made it look more tech/contempory
2. Most importantly I read in multiple places that the aluminum was more rigid an stable and even Magnepan commented to it being better performing material by a small margin for intended purpose.

If I trade up to 20.7s I am getting black on black.
