How do you feel about your Aleph 5 on them? I cannot see as how the Beast would work, or really any OTL for that manner. It is spec'd at 160 into 8 ohm, and 110 into 4 ohm. To me that indicates that it will not mate well with Magnepan 1.6s as they seem to like current. I have attempted to use an Aleph 5, and didn't like it on them- lacked PRaT. I attempted several 100 w tube amps and had the same issue. These were not wimpy cheap amps either. It always reminded me of the old days when I first go into tubes. I was trying to run MG 1s with Dynaco ST70s or Mark VIs. There was a hint of greatness, but I was always left wanting. It was not until I installed my Parasound JC 1s (400w/800w) that they awoke. I do not listen loudly either. It is about dynamics and low end control.
