Turntable isolation

I'm thinking about doing the same thing with my Thoerens TD125.

I just called a local granite counter top dealer and they said they can sell me a 24" x 24" x 2" piece of granite for about $35. Anyone see any issues?

I know in the manufacturing world they use granite slabs lifted by air, water, oil, etc to get truely flat and vibration free surfaces.

Hello,

A butcher block on top of gel mouse pads. Total isolation on a ROCK solid platform.

That's what I use under my Technics DD, except I use keyboard getl pads that run the width of the cutting board.

On the top side a set of PartsExpress brass cones are screwed into the bottom of the turntable with their adjustable points removed. This leaves a concave surface on the underside of the brass cones. This assembly is then placed on top of Vibrapod Cones. The steel balls of the Vibrapod Cones fit right into the truncated brass cones' concave surfaces.

I use an 4 inch thick block of mango wood, sitting on top of four 1 inch square erasers from the local school supplies store. This all sits on top of my teak stereo cabinet. Not a hint of vibration.

The sound of my Rega was greatly improved when I put 3 Cardas blox under the surround. Probably dominoes would work too.

This magnetic levitation stand looks interesting:
