Nandric,
I did not take the time to swap stili between bodies. All of the 3.5mv Mitachi generators most likely sound the same or very close but to be sure, I will experiment later. I think I have six different bodies between Astatic and Glanz. Could prove interesting.
The MF-61 has its own booklet that mentions no other Glanz products. As I posted a while back, all it says is that "MFG-61, as the most prestige model among Glanz cartridges...". My sample came new in the box. Under close inspection I am sure it had never been mounted or used. The cantilever is boron but it is much smaller in diameter than the boron cantilever supplied these days by Ogura. I would guess 30% smaller. I bought it off eBay many years ago before I had read the MM thread on A'gon. I had been studying cartridge designs and moving flux and moving iron seemed to be the best design, in theory at least so I was buying cheap samples to try. It came from Peru or Portugal I think. I did see one listed a few years ago. I wish I would have bought it but at the time, I had not yet tried the MFG-61 and had no idea how special it is. Silly me.
