Use of footers on maple platforms

I know this has been discussed elsewhere, therefore I will try to be specific with my question.

A Maple shelf is thought to dissipate vibration from component resting on it. Would not isolation feet/dampeners inhibit this? Does the replacement of the original feet on a component with cones benefit the dissipation from the component?

I have just replaced the plywood selves of my rack with 2" maple ones. Was using vibrapod footers with the plywood shelves. Currently not with the maple.
