High End cartridges and the built quality

Thanks for the info 99, it is disturbing to me. To Markpao and Whatthe's point, how much do we really know about anything unless it is magnified? And how much do we want to know? I now feel like I have been lucky with my 2 cartridges since both play with no "known or detected errors."

I know cart are built by hand by craftsmen and as such there has to be a margin of error. But once complete how does he/she inspect and determine that it is ready for consumer use and enjoyment?

I am in the market for a cart and it is already a daunting decision because of the numerous options, things like this give me great pause....

To the cartridge designers and builders I say "Come On Man!"

Whatthe, you have it backwards. Cartridges are assembled under very powerful microscopes, with far higher magnification than that shown in these photos. The higher magnification should make more accurate stylus alignment not just possible, but easier and more consistent.

I think it is not so difficult to align a diamond within 1 degree. The problem is, nobody of us users was interested in this case and we have payed the money. I earn my money with milling miniature pieces for aeronautic. If i have such tolerances, i really would have a problem.

M = hight of gravitational center
Y = quasi static lateral force
? I am just asking ✌️

Very interesting thread. I recall meeting Dr Feickert and he told me that Ortofon are in fact the most consistent cartridge - perhaps due to the fact they are one of the bigger manufacturers.
