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?

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.
We sell cryo'd springs. Should work fine for anything under say fifty lbs. is it wrong to say that?
I replaced the springs on my VPI/Denon with double sets of Symposium roller blocks with great success. The music came to life.
Squash balls. Make your own platform(s) and it all costs almost nothing, or use Ginko.
Rpfef: Yes, I have years of experience and am currently using mine. While all of the above posters who have used a lossy rubber or sorbothane type of interface, receive some sonic benefit, these do not result in the optimum performance this table is capable of so it isn't the "cat's meow". The best way is a "direct drain path outward" for vibrations/resonances to dissipate completely. These other options don't meet that critical criteria. I think I posted some of it early on the ET thread.

(Years ago, I also) made a set of "helpers" that I use in order to extract the plinth from the base for easy maintenance and so-forth.

If you are interested, private message me for more info.
