Any tweaks recommded for under cd player?

Rollerblocks of any kind have always worked well under the transports and CD players I've tried them on. They provide some isolation while enhancing a clean and crisp sound, kind of like spikes in that way but with built in vibration control to boot.

Enjoy,

Pick any three mentioned thus far and try them.

As you can see, there is seldom a consensus recommendation when it comes to tweaks.

Oh yeah, I'll add Grand Prix Audio Apex footers...

I've got my Meridian on a Neuance shelf (neuanceaudio.com), on top of some small Michell tenderfeet (available all over). Didn't try anything else before this setup in terms of isoloation, but realy pleased with how this combo works. Can't speak to what it may have done for extension, but the improvement in focus and pacing was palpable.

Any one tried the marigo labs mystery feet?

Over the years I've tried BDR Cones [didn't like either flavor], Blue Circle cones, Mapleshade brass cones, but liked the Neuance Shelf the best.
