I do not think that the 3 motors example of Clearaudio is applicable. Theoretically it correct and a single motor driving a platter coastally minor-swing it on it’s bearing. In realty the things are more completed. With enough mass of platter the force that yank the platter when the belt “drives” become negligible and is not sufficient enough to allow any platter micro-playing. Furthermore the Micro- Seiki player are not sitting on a bearing (Model 8000 has no bearing as all under bottom) but a cushion of air low pressure air that very effectually dump the micro-playing, permanently (sine the platter reaches the cruse momentum) reacting to the driving force that applied to one side of the platter. Even further, some the Micro 8000 motors tune themselves to the tension of belts. In real live this feature do not work with larger Micro platters as they, given their kinetic force are quite stable in this gyroscopic inertia.
Also, the Clearaudio is wonderful demonstration how ebon the conceptually proper theories might not have any relation to Sound. If you listen this 3-motor turntable by Clearaudio then you realize that the misery of their sound is far further then the amount of motors they use. To talk about platters star-driving in context of Clearaudio is similar with assessing a LF of an amplifier in context of mini-motors that have -3dB at 80Hz ...
I myself like the “F” configuration a lot and I do not care about the slippage. The slippage might be modified by approximation of the motor and the idle roll to the platters and changeling the angles with wish the belt attach them. I even thought to valance with these angels (by managing slippage) the differences in the TT mass and the differences in the platters inertia. I juts do not think that I would have enough room atop of my stand to organs the “F” configuration in a way as it should be.
