DIY turntable plinth material

We have slate, corian, Delrin, and wood. PBN wood plinth looks too raw, but slate or corian will probably look un-proportional since plinth will look much thinner than VPI super platter which is nearly 2" thick.

I read an article comparing plinth material based on mechanical properties like stiffness, damping factor, and resonance freq. Acrylic seems to be the most ideal material, but reality is acrylic plinth is too dead sounding and many manufactures have moved away from acrylic plinth. I know I ant some wood in the plinth, but if corian or delrin is better, I don't mind giving either a try.

I agree that Delrin is a wonderful material for turntable use. I have no audio experience with Corian, except that I do know it works easily.

MDF, on the other hand, is a material that is like lead in that a little goes a long way. Be careful with it because too much will result in a dead, non-musical result. I believe that it is best used in combination with a more lively material.

Corian is not resonance-free. Using the standard 1/2" thickness, it was necessary to add a layer of heavy damping to the underside to stop the ringing (which is higher in frequency than one might expect). A layer of Dynamat was the cure.

Go for Panzerholz or Permali.
