To isolate unit from any table/support vibration?

You may wish to investigate Terracone and Terrastone products from Edensound. Dan Sherbrook is very helpful and knowledgeable;   his products are highly effective. I have many of them under all my components.
I agree with @arsh, I've been using Edensound's TerraCone footers (w/ point-receivers) on my VPI and it's made a big difference. Sound is more detailed, better dynamics, better bass. Dan offers a no-obligation 60 day trial so you can demo with little risk.
