My TT and sits on a 3/8" thick piece of granite.
The granite sits on a 3/4" thick MDF shelf.
Between them is a 1/10" layer of foam
- i.e. the type with holes that you put under a rug to stop it slipping.
- this kills all vibrations in both the MDF and granite
Between the MDF shelf and the steel support for the shelf are 1/10" thick pieces of sorbothane - this kills any vibration from the rack & floor
The TT itself weighs around 25 lbs and has 3 ball bearing feet that sits directly on the granite and between the ball bearing and the TT plinth is another piece of sorbothane
I’ve tried lots of other methods and this is the most vibration free I’ve managed to get it to date.
I use the granite/foam/MDF for all my opponents - I just adjust the size of the granite/foam to a size closer to the size of the component - e.g. my phono stage and DAC sits on a 5/16" thick, 12" x 12" granite tile which sits on the MDF with foam in between
From this experience I believe the key is to build a shelf from a sandwich of vastly different materials
But - I'm always on the lookout for new ideas :-)
