Excellent turntables with threaded spindles ?

For me, I would avoid using screw on record clamp at all cost. The reason is that the spindle is usually an extension of the bearing shaft with has direct contact to the ball bearing/thrust pad....If using a screw on record clamp on the TT, the grinding noise from the ball bearing/thrust pad will transmit throught the bearing shaft to the spindle then to the clamp, LP and noise will be pick-up by the cartridge. The 'screw on record clamp' is not well thought design. A record weight or damper is a better choice.

Yes, the theory will apply to your mentioned method too. I used to have a light weight Michell LP clamp...I used it a few times and sold it. It was not worth my time.
