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.
High End cartridges and the built quality
I had some cartridges in the past with some quality failure. Only one, an EMT was perfectly built.
Here some pictures of Lyra Skala and Kleos cantilivers/diamonds:

I think in this price range not acceptable.
I know a Dynavector Xv-1s with the same problems.
