Any tweaks recommded for under cd player?


I have a lector cdp7 cd player looking for some tweaks under the cd to get a little more extended on the high?
Any recommendation out there?
Thanks in advanced

I think a leveled player is important as well, so the sofa cushion intrigues me. I had the walker audio valid points and replaced with the Finite Elements cera pucs-very happy with sound. I do agree that power cord, line conditioner and interconects-balanced for me-are the foundation, and then, isolation. All work together with synergy and then, when it all clicks-along with a great cd player, preamp, etc, digital, well, finally sounds good. SACD does blow my mind. Not always the emotional connection that vinyl gives me, but a very pleasing, musical experience.
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.
