Thuchan, I was only joking when I mentioned using 3 or 4 motors. However I think there actually was or is at least one commercial product with 3 motors as an optional “upgrade”. In these discussions, it is my tendency to favor direct drive and idler drive over belt drive, but I certainly do recognize that there are very fine belt drive turntables that have sounded wonderful to my ears. As I noted earlier in this thread, I think, the Doehmann helix turntable is one of those latter. But you have to spend what is for most of us big bucks in order to get to that level of performance. And lesser levels of belt drive turntables just don’t cut it for me.
Richard, I was surprised to read your comment about the difficulty of designing and building a direct drive turntable. With respect to vibrations. Because to me a saving grace of direct drive is that there is no physical contact between the motor and the platter, the platter itself is the rotor of the motor. It is driven by the magnetic forces generated at the stator which never touches the rotor. So the only issues are accurate speed and speed stability despite stylus drag, bearing friction, etc.This is not to say that designing and building the world’s best direct drive is not a challenge, but I would have thought that one of the challenges is not motor noise of the mechanical type.
