What's under YOUR CD player?

Neuance! (under the amp too!)

After reading all the posts, I've purchased and installed (tonite) the 'new' Nuance "bad boy" isolation device.

It's thicker than the Alpha or Beta.

Supported it like subaruguru did, with the included stock threaded spikes that I drilled/tapped into the Walnut shelf of my cabinet.

It looks cool, but OK, how do I tell if it's really doing anything to the sound?

I've experimented with foam pads of various densities, with mixed results. Now that my CD player is enclosed in a heavy custom oak cabinet, with nothing under it except the stock feet and the oak shelf, it sounds better than ever.

JBatlanta, Now that it's installed allow the whole set up to sit with no tweaking for at least four days. The Nueance needs to settle in to each alteration of support. After a few disks you'll know! Take it out and listen, the change is easy to hear.

Poor man's isolation.
Buy a mouse pad from computer store, cut it to the right size. put it under your CD player or turntable (you can double or tripple if necessary). Always remember to level your player. One or two dollars and 10 min of work.
