Dear Henry, if you want this thread to soon get out of hand, the best way is to encourage the idler-, belt- and direct-drive "camps" to start a discussion about what is the "best" drive system for turntables .....
This is a minefield full of personal preferences and highly explosive "sensibilities".
Especially so, as each and every of the popular drive principles does have special requirements to the tt-design as a whole.
Better leave this alone .... it won't do any good to the Copernican view of the turntable.
Cheers,
D.
