For 1 year I use a drumkit of this series and the difference with MRX Series MMX example lies in composition ca 6-ply maple instead of 4 for MMX it increases the projection of sound and makes it easier to resort the sound of his drum group is not for nothing which was designed to live. The price of this snare is very upscale but no free lunches in our day, by the way I waited a year and a half since this series is only on order. I probably do it again this choice.
