So I've never heard of this and had no clue as to what you meant. It took a little bit of googling until I got the right search words to bring up what we're talking about. Fascinating. So the idea is that anti skate is more destructive than tracking errors, mostly because there is no correct anti skate (anti bias) setting that is correct across the record. So you eliminate the angled head shell and align straight on the tonearm axis with only one null point somewhere between 60mm to 70mm from the spindle.
Supposedly this results in a much more dynamic sound with added depth and bass weight. The greater tracking error either doesn't matter, or results in pleasing second order harmonics, depending on who's speaking.
It doesn't appear that you can use any straight tonearm as infired by the OP, it requires a special tonearm and head shell. Do I have this right?
Regardless, very timely post on an interesting subject.
