Vibraplane

Sounds like both examples above use the table with suspended design(Simon Yorke , I think and VPI). Does it/will it equally effective with Non suspended design?
I guess the intent isto isolate the TT from cabinet/rack regradless of type of TT design, so you would think it will work well with either design. May be more users will chime in...

Sirspeedy,

You may already know this, but for those who do not, Vibraplane used to or still does rebadge Newport Research scientific isolation platforms.

Newport specializes in vibration control and isolation surfaces for scientific and critical high-tech testing equipment. You can often find surplus units for sale on eBay at 1/3 Vibraplane's new cost.

Newport(and a several other companies) also make constrained-layer scientific/research breadboards that I think function exactly like Symposium, Bright Star, and other isolation platforms - perhaps to an even higher degree because of their clientele.

Might be worth looking for some surplus platforms if you are the value shopper I am.

Sorry!I did not mention that both VPI's used were not with the VPI suspension,but a fixed one.

After the VPI I have been using on my unsuspended Redpoint Testa Rosa and it works really well.

Any information on the performance comparison for the Minus K and the Vibraplane will be greatly appreciated.
