@skyscraper - I use...
for amp and turntable
- 3/4" MDF shelf
- 1/2" 18" x 14" granite tile (cut to tat size)
- with tool drawer liner in between them
Tool drawere liner like this product
https://www.banggood.com/3x0_3m-Drawer-Padded-Shelf-Foam-Black-Box-Liner-Non-Slip-Lining-Grip-Rubber...
I buy it from the dollar store - very cheap :-)
For smaller components (phono and Bluesound Node 2) I use 3/8" MDF and 3/8" granite tile with the same drawer liner between them
Each shelf has sorbothane between the shlf and the Rack;’s metal frame
My TT plinth is also made from 3 sheets of 3/4" MDF glued and clamped. It is very dense and does not vibrate - I would have to believe 2 sheets glued would make a very good shelf.
Each component is currently supported by 3 wooden feet like this...

The Amp and TT has the large feet, the phono stage has the medium feet and the Node 2 has the small feet
The wooden feet made a noticeble improvement in the size and precision iof the mage.
I have heard good things about Mapleshade product and their web site may contain some useful info for a DIY person
Hope that helps - Steve
