re: does this design isolate from the supporting structure or does it not?

In the top photo we can see that the three spring studs are located on 3 footers which, in turn are situated above 3 rectangular blocks of some unknown material.

As I view the photo I notice that it is the adjuster nut, located at the bottom of each spring, that makes physical contact with the footer. --(the nuts are locked into position by means of the screw threads they fit onto)-- I suppose that the three foot pads offer some sort of isolating quality. However the contact between adjuster nut and footer is a solid mechanical contact. In this configuration the only thing the springs support is the motor plate and everything attached to it. I presume this to be a lighter load than it would be if the springs were supporting the subchassis, platter & bearing and tonearm/armboard.

The only thing the springs isolate from is the motor plate with motor.
