Since belt drive tables are perfectly satisfactory for audiophiles and
direct drive ones perfectly satisfactory for DJs, why reinvent the wheel?

Why not give audiophiles the same advantages as DJ's? Don't they deserve
to have a table that has the best possible speed accuracy?
What is the basis of your notion that mainstream
turntables produce *audible distortions* due to
speed inaccuracy?

Speed Accuracy (±%) Examples:
Basis 0.1-0.05
Clearaudio 0.1-001
L.A. Michell 0.5-0.25
KAB 0.03-0.005
Nottingham 0.05
SOTA 0.1- 0.04

What is the threshold of acceptable distortion,
in your opinion?
