Best material for isolation purposes

I have been very happy with the Symposium Ultra platform, I use them under my EAD Pre/Pro and my Levinson 37 transport they come with coupling blocks or for over the top performance try Nordost titanium pulsar point or the symposium rollerblocks in combination with the platform.You can track them at www.symposiumusa.com ask for Peter He is great to work with and www.nordost.com for the pulsar points

I'll have to second the Symposium reference. I use rollerblocks under my tube phono stage and under my tube amp. Ultra platform under my turntable, I plan to buy more of their products...very noticeable improvements.

If you want to try something cheap, go to a kitchen store and buy a thick maple cutting board...I bet you'll hear a change.

MarkOne; because of the existing products we manufacture; and recently getting involved in a real hifi analog system myself; I had my factory load as dense a material they could a new form of acoustic putty if you will. I placed some on top and on the front face of my speakers, and under my TT. The result to my novice ears was stunning and everyone who has heard my little experiment heard t as well. I was actually developing the material for an equine product. A any rate if you would like to test some out let me know and as long as you will sign a non-disclosure will send some out to you. Best of luck

I use (4) sorbothane hemispheres underneath and (6 - 8) Black Diamond Racing cones on top of my preamp.

Aurios Bearings- You'll be surprised.
