Not sure what your system set up is, but I removed the springs from my PL 15D and replaced them with solid chrome bolt points (with sorbothane pads on the flat side). Improved the sound tremendously. I am on a concrete floor so vibrations are not an issue. I did a lot of upgrades to my TT - all cheap and easy...Isolate, isolate, isolate. Its the best you can do for your vinyl. Good luck.
