Before you sign on for expensive mods, why not start with some Vibrapod cones and isolators. I use Vibrapods under much of my gear, and I just put a special arrangement of Vibrapods under my turntable which has catapulted its performance to the next level.
For as little as $56 and no shop time, you could find out how far the Vibrapods take you where you want to go. See here and here.
Disclaimer: I have no financial interest in Vibrapod; I've been an enthusiastic customer for over a dozen years, and they sometimes still surprise me.
