I don't know. I'm in the camp that believes that it does. For instance, the best thing I ever did in this area was Mapleshade's maple with their rubber, cork, rubber footers for my turntable. My previous setup was Nuforce 8b's on isonodes on a Classe amp on that same isorock platform. I put my 8.01's directly on the isorock. I haven't really thought further about it because, first I will be changing this, and second other areas of my setup, I believe, are more in need of looking at.
