Well I'm not sure how much of what's written is applicable today. Today's arms and cartridges typically track a lot better too. But there were some other good take home messages. Certainly the points regarding stylus/groove contact areas and relationship to SRA (would be interesting to see Peter Ledermann's comments on Mitch's piece).
I was corresponding with Harry Weisfeld (I think Mitch was involved with designing the alignment for the VPI arm) and he reminded me that Mitch had some other articles in the old Audio Critic, that is before it became the piece of junk it is today. I'm going to try and find them if I can. People kinda forget Mitch and his role in the development of high-end audio. He made a lot of great products in his day.
