I remembered your article in Audio, as it had a graph of distortion vs. angle which showed the different effects of VTA settings (less sensitive) vs. SRA settings (deeper distortion null at correct setting). I must not have the eyesight you've got, 'cause I can't see the line of contact on the stylus with my old eyes. I used to do X-ray crystallography research and I was used to aligning crystallographic axes with the beam using a goniometer head (this had vernier scales allowing changes in angles of 5 minutes of a degree of less). Wish we had these on tonearms! I want to know how stylus manufacturers cut and align the diamonds to mount into the cantilevers. If they used laser diffraction, the differences would be much more visible in "reciprocal space". If this works, audiophiles should also be able to use laser diffraction and correct azimuth, offset angle, and SRA using the much larger reciprocal space pattern. I once aligned an JMAS MIT-1 cartridge using a microscope to view the stylus/cantilever actually playing the groove at one of the two null radii. What was scary was that before alignment, I could see the diamond shaving off vinyl like orange peel with every rotation. I became a fan of LAST record preservative at that point, as it reduced the shaving problem significantly.
