DIY turntable plinth material

I have a spare VPI super platter/spindle, thinking of building a TT out of it.

I have some materials in mind

I have a spare BDR shelf that I can use, but its difficult to work with and will only consider if it offers significant performance upgrade.

I can have acrylic or MDF cut to any shape, both are easy to work with. I once had a 400lb granite but I can't possibly imagine using it due to the size and weight.

I assume a mixture of different materials should offer the best performance, wondering what do people use to build their TT?

Planning to use my Finite Elemente Compact for feet, they offer tremendous performance. I also have some BDR jumbo puck and cones I can use as well.

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.
