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.
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?
