Vibration platform for Basis Turntable ?

My experiments with the Basis Mk5 with Graham Ceramic +Tungsten arm, (when I owned it), was that any device (re:) Black Diamond Racing shelf, Purist Audio Platform, four inch Granite, solid Maple butcher block shelf, etc. all were detrimental to the sound.

The Plexiglas making up the lower platform of the Basis seemed to reflect or react with the device directly beneath it, regardless of size or materials it was constructed from.

Best results were finally had by using the stock Basis feet sitting on a four inch diameter, four post stand with open architecture. Constructed from aluminum and filled with silica.

Best results are obtained when the stand and turntable are kept fairly close to the floor. The taller the stand, the less effective, especially on pier and beam foundations.

I use a Zoethecus rack with the Z-slab for my Basis 2500 and am very happy with the results. a big improvement came when i built concrete slabs and posts in my crawl space to reduce foot-falls and feedback from my suspended wood floor.

A.J.Conti of Basis states that he has yet to find a rack that has any positive affect on his fluid-suspension turntables. I wouldn't go that far but i do think they are better on a solid rack than some isolation device.

I also wonder if i can improve the performance with some sort of isolation device but the Basis is designed to work on a solid rack so i will stick with what i have.

I do not have a Basis table but use the vibraplane under my VPI and was the equivalent of a major component upgrade. I do not see how you could go wrong with it.

We are using a Vibraplane 2212 Active platform and to tell you what I feel is the truth, it is a marginal improvement if at all given the superb Basis suspension.
