I am a small VPI dealer and one of the best mods was to replace the stock feet with something like the Star Sound Audio Points. The 1/4 20 threads screw right in and 3 of my customers were very happy with them, another is trying them out now. I sell these but others made of solid brass should also work. I have a Michigan Maple block resting on a VPI TNT platform under a Classic and it works very well; I also had it under a Scoutmaster and Scout. I have FIM ball bearing isolators under the Maple block, this works even better than brass cones, which are also good. I am a FIM dealer also. The VPIs respond well to tweaking and there are many roads to try.
