Cones/Bearings for CD player

I don't care for tonal shifts caused by cones, but Aurios
MIB and Symposium Rollerblocks can be very effective under CDP with internal rotation vibration. I fully agree with Albertporter. They also are close to nuetral with tonal shifting. The only problem is stiff/heavy ICs and AC cords can make set-up, hard to impossible.

The proof of their value is you see used Aurios MIB sell almost instantly here and at little discount to retail price. I have some polycrystal cones but don't use them,
I do like vibrapods and partially inflated bicycle tubes for some applications. All these produce different tonal shifts in sound, as well as different degrees of increased
detail retreval. These are just one piece to the puzzle,
along with ICs, AC cords, racks, etc.

Ernie (Subaru), is your neuance shelf directly contacting your metal rack, if not what is between nueance and rack? Also do you directly couple the metal body of you gear to the nueance shelf, or do you keep existing feet on gear?

Same queation for Dave (Dekay)?

Just to clarify about "coupling" component body to nueance shelf, I am not asking about removing stock feet, but Symposium shelfs/platforms supply small blocks of solid metal called "couplers" to bypass stock feet and directly
connect/couple component body to metal surface layer of shelf.

Everyone seems to love their nueance shelfs with stock footers, it is amazing that they can work so well given the wide range of different designs/materials used for stock component feet. Although it sure makes life easier, listen to the music and forget about support/footer tweaks.
