I haven't worked with your model 19, however, any VPI that I have worked on benefited from removing any movement from the tunable. I have used Bearpaws, or Audiopoints to solidly attach the table to the supporting rack eliminating any feet (mini feet, etc.) Try it - you can always go back if you don't like it.
Alternative for VPI springs?
I have an HW19/IV with the standard spring suspension. I have often wondered if the performance could be improved with a non-spring suspension. It seems the favorite substitute is Sims Navcom Silencers, no longer available and rarely offered for sale used.
Is there anything I can actually get that does the job well?
