RE: For non-DJ buyers...

For iron-core motors, like the ones Technics used back in the late 70s, it's all in the number of poles. The more poles, the less cogging would be detectable. Also, I suppose it depends upon the sensitivity of the instruments used to detect cogging. Anyway, I think that what some DD critics describe as "cogging" is actually due to the action of the servo to maintain exact speed. This is true of the SP10 Mk2. The SL1200G now uses a coreless motor, which IMO is a major upgrade over the old SL1200.
