Drive System

Idler wheel drives in general were originally designed to overcome stylus force drag, as in their day cartridges tracked at 10 grams.

As expected, sudden transients, dynamic shadings and bass are, apart from actual tracking force, the greatest causes of stylus force drag, which is always present, and it is here that failure to overcome it is most audible.
