Hi Steve,
I added the double belts out of an abundance of caution when I bought the periphery ring. The ring adds considerably to the mass of the platter of course. The belt(s) stretch particularly on start up, but also albeit much less, as the platter turns. Think of it this way, the platter slows a bit, the torque of the motor pulls on the belt to correct and the belt stretches. The platter speeds up and the belt relaxes. And so it goes with the belt stretching and relaxing repetitively. Double belts = less stretching. This phenomenon is independent of the Phoenix Engineering or SDS psu systems. Is it a big deal? Of course not.

Years back with a TNT I found it actually was a big deal to dispense with rubber belts altogether and move to a tensioned thread. Easy to do with an outboard motor. Perhaps someone will try something like this with a Prime.
I love it! The lengths we go to in the pursuit of better sound! Thanks for sharing. BTW, I agree with you completely that belt stretch is a factor in the sound. The difference is quite easy to hear between my Prime and GAE, when compared back to back. Without being able to compare, though, it is doubtful that it would even be noticed much less bother most people.
