Apogee Duetta vs Mangnepan 3.6r

I have never heard the Apogee Duetta speakers and was wondering how they compare to the Magnepan 3.6rs. The Apogee Duetta would probably be a good match for my Sonic Frontiers Power 3 tube amps. Are there any draw backs to buying Apogee Duetta speakers this late in the game? What about support?
