The Magnepan arm is a unipivot. One of the comments against unipivots is poorer bass than conventional arms. But if I'm not mistaken the area above the unipoint is extra heavy on this arm. I once experimented on a unipivot and added mass above the pivot. The bass noticeably improved. I suspect the Magnepan arm has very good bass for a unipivot.

I remember the very first time that I used a unipivit arm. It was at Ribfest at ... - J. S. Bach 18:40:53 10/22/23 (0)
...MusicMike's the action/motion/whatever compared to what I was used to scared the heck out of me; I thought that I had broken his tonearm. I got used to it after that but, in reality, I still would not want one. My Syntec S-220 does the job well enough for me on my Technics SP-1015.

It certainly does !

I suspect the reason is ... the way it is configured is that the downward=pointing spike rests in a ball-race - not a cup.

  didn't know it used a ball race. the arm I played with, a Keith Monks also used a ball race which was why I mass loaded it knowing the point wouldn't be dulled.
  
  By the way the Keith Monks lifted of with no disconnections. The arm had 4 points that fitted into mercury baths to conduct electricity signal. That's probably why it went out of production. Besides the open baths of mercury, the mercury was not a great conductor of electricity and when low output moving coils came out the mercury was a disadvantage.
