Harold, You are welcome to dissect the wonderfulness of the L07D and attribute that quality to magnetic levitation of the platter, but I think that misses the point. IMO, the L07D is transcendent because in its design every aspect of construction and function was considered and addressed in one single product, from plinth to headshell. One may quibble here and there with some of the choices that were made, but there is no denying that the L07D's excellence is the product of its "whole-ocity", if Harvey Rosenberg will forgive me for borrowing his parlance.
Doron, I have never seen in person an EMT927, but in my mind the EMT927 and the Lenco L75 are at opposite ends of a spectrum; the Lenco is on the "less is more" end of the spectrum, and the EMT is on the "more is more" end of the same spectrum. The business of torque is a mystery to me, because there is to some degree a correlation between torque and performance for dd and idler tt's (leaving belt-drive out of the discussion), but with some exceptions. The Lenco has a physically large and powerful motor, but the torque that can be delivered to the platter is always limited by the coefficient of friction between the idler wheel and the platter surface that is in contact with the idler wheel. In a Lenco, that contact patch must be small, because there was a negative trade-off to using a wide idler wheel, as is typical for idlers that drive the inside rim of the platter or the outside edge; a wide contact patch would cause "scrubbing" in a Lenco, between the idler wheel which "wants" to go in a straight line and the platter, which must rotate in an arc. So, the torque of a Lenco is truncated by the force required for the wheel to dissociate from the underside of the platter and skid. If you grab the platter, you can feel that happening well before the motor comes to a stop.
