Which cone's or platforms have helped?

I just read about a tweak using Styrofoam instead of platforms or cones, so I tried a solid block of 3" thick Styrofoam the exact size of my CDP and DAC (preamp and amp also).

I placed each component on it's block and the clarity increased dramatically. Passages that were entirely unintelligible, I can now understand every word clearly. The difference was hard to believe.

Try it, its cheap. If it doesn't work for you try something else. But don't be surprised if the results are as good as the most expensive options.

This was just regular old white Styrofoam. The hard stuff. Well, it's not really hard, you can dent it with your finger, but I had several blocks that were used as packing material in a box that was just shipped to me.

My suspicions as to why it works so well is that it is mostly air with thousands of cells joined randomly.

I placed the components on the Styrofoam bases without the component feet attached to the component. Just the bottom of the component sitting on top of the block.

Sorry I can't be more descriptive of the Styrofoam, but I thought there was only one basic kind.
