More from this interview with VdH:
“What I learned was that in the playing position the arm must always be somewhat higher at its rear end (the counterweight end). A 9 to 9.5 inch arm around 7 - 9 mm higher. This improves the resolution a lot. Works with any arm and any cartridge. What you have to keep in mind is that each record is different. So fine- tuning the spatial resolution is slightly different per record. This can be fine-tuned by changing the distance between the arm bearing and the mounting board.

One millimetre up or down can be enough. But the average of 7 - 9 mm up works always in your advantage.”
