Eric WRT isolation - for my turntable I currently employ the following...
- a 3/4" MDF shelf with a 10mm granite tile cut to size and foam shelf liner in between - like this

- the Turntable has ball bearing feet, which I find is superior to cones because they "rock" if there is any movement in the granite - that movement is not transferred to the TT
Spikes actually grip the granite and transfer minute vibrations to the TT
You can make your own very easily - here...

I have removed the rubber feet on my TT and simply mounted the Ball Bearing feet to the bottom of the plinth. The sorbothane will naturally adhere to most surfaces (by vacuum) and can be removed without leaving any residue.
I use variations of this approach (i.e. different sized ball bearing and washers) on all my components and finds it works extremely well - plus it’s very affordable
The commercial sorbothane products I’ve tried apply use too much sorbothane and results in a muddy reproduction. The thickness of the sorbothane is important - I use 1/10" sheet only.
Hope this helps - Steve
