It is very good speakers, detail,claer and good bass. At first, it is afraid that my MF A3 cannot push it well, but after changing the power cord, the speakers give u tighter bass. And it is no problem about it. Maybe higher dyna(1.3se) models will have this problem.
When I tested this speakers, the sales used Krell 300i to drive it, it gave out better bass but the MF won the treble and air.
Now,the sound is still changing became better and better, I think it needs 1 year to mature.
