High End cartridges and the built quality

99- The picture quality is quite amazing, the quality control not so much. These are very delicate items, but the failure of QC to detect these problems is very disappointing.

The magnification used to make the measurement and take the photo does not affect the extent that the diamonds are not "plumb and square". The only thing the microscopy does is allow the user to see and measure the degree (pun intended) to which the stylus is "out of spec". With respect to a line contact or micro-ridge or other exotic stylus shapes, where the contact patch is so small, a 4 or 5 degree error is, IMO, substantial.
