I have a Garrard 301 mounted in an Acustand Solid Plinth2, so I don't use a separate platform. Just three IsoAcoustics Orea Indigo feet is all I need. My 'table sits on a heavy mid-century modern buffet. I can strike the buffet with a mallet while an LP is playing with the plinth sitting on the IsoAcoustics feet with nary a skip or a jump. Strike the plinth itself the same way and all hell breaks loose. I used Sorbothane footers before the IsoAcoustics Orea feet and they were about half as effective.
