Any tweaks recommded for under cd player?

"Ceramic" foot sanding stones at Walgreen's etc for ~$5.00.

goone: The mystery feet work very well under my cd player.

I tried Herbie's Tenderfoot under my cdp. It improved the quality of the denon cdp.
Has anyone else tried these Herbies Tenderfeet and did they find anything that was better?

I also tried cork/rubber anti vibration pads and they also helped a little.

Use Aurios under my CEC TL-1X transport after trying many other solutions (Ceraballs, Plycrystal, BDR, etc.) Aurios was the ticket.

Same exercise under my Dodson 218 DAC. Result: Herbie's Tenderfeet best. Fleshed out sound, wideneded soundstage. Immediate audible improvement.

Only way to know is to experiment, unfortunately. Too many variables for one-size-fits-all solution.
