Dear @best-groove : """
From what I read then aluminum is dominant in cantilevers for several expensive... """
no, it's not that way only some models. The SPU case is especial because the 80% of sales are made in Asia and Japanese are so idiocincratic in that cantilever material regards as in other audio items.
Dynavector use diamond and boron, Lyra use Boron, Ortofon diamond and boron in its top models, VdH use boron, Benz-Micro Ruby and boron, Sumiko use Boron, Air Tigth Boron, ZYX boron, My Sonic Labs boron, Koetsu diamond and boron, Clearaudio boron and I can go on listing today tops cartridges but even in the past too berylium, diamond and boron were the materials in the top model cartridge cantilevers: AT, Audio Craft, Audio Note, Technics, Sony, Dynavector, Yamaha, tec, etc.
Aluminum in the FR was what the designer like it more when he voiced his cartridges. Cantilever is an important part in the whole cartridge desing but only one part and in the voicing of the manufacturers we are in the " hands " of the designer bias to some kind of sound he was looking for.
Aluminum in the Magic Diamond was or is used not because is the best material but first because use the same cartridge motor of the Denon 103 ( aluminum cantilever. ) and second because was what the biased manufacturer like it.
I had the opportunity to listen to the MD in a first rate system: Walker TT/tonearm, my Essential phonolinepreamp, speakers by Kharma and the like and is nothing to die for, a good cartridge but nothing more.
Maybe in the future when boron disappears aluminum will grow up but not before because it's an inferior material than boron, saphire, ruby or diamond for cantilever cartridges.
