Springs for homemade isolation stand


I want to suspend my granite top from my Sound Anchor rack w. some springs to create an isolation stand. I have about 100 -200 lbs of equipment on the granite top including a turntable. I was wondering if anyone can recommend a source for the springs that can support the weight & control resonance.

Dgad,

Calculating the resonance frequency of a spring with unknown physical properties is impossible. There is no way to predict whether the outcome will be better or worse, save by trial and error.

Springs also introduce the possibility (certainty) of lateral motion. This could have positive effects but for a TT I'd expect the net effect to be negative.

For beneath your Hyperspace I'd suggest three Stillpoints with risers and inverted risers. You can see them on the Teres website with the model 320. They worked wonders for the noise floor of my 265 and 320, with no real sonic cost in dynamics. Highly recommended for isolating a high mass table from floor/stand vibrations and dampening plinth vibrations at the same time, without allowing unwanted movement.
