I am pretty sure you will notice a change in sound if you replace the marble with another material. I don't have any experience with Vibrapods but I have certainly tried lots of other isolator materials, and while they impart their own sound to the system they still allow you to hear the effect of the material under the isolator. For what it's worth, I think marble is not a good material to use a base or platform in a hifi system. It has an unnatural coloration IMO.
DIY TT platform Marble to Wood Changeover
I have a Basis TT without any suspension. It is wall mounted
using a steel bracket which was originally an amp stand. The shelf is white marble and separated from the rack with rubber strips at the 3 contact points.
The TT is isolated using 3 Clearaudio acrylic cone feet sitting on Vibrapods. This works pretty well but everything I read says marble is a no no for this application. My question is this. Does the marble really play into the sound if it is separated by the Vibrapod/cone feet? I would consider changing the shelf out to a birch board or butcher block. If so do I keep the cones and Vibrapods?
