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.

Wait till you're feeling lucky before you make a decision, 'cause it's kind of a crap shoot. Agree with Sam above -- lot of products shift tonal response, but you might find one that complements your system. I can see how bearing supports give you a good shot at neutrality; I haven't yet rationalized the expense of trying them in my low-cost system. I think the Neuance shelf also is good for providing a neutral baseline for your equipment. Be coldheartedly clinical when evaluating any of these devices -- easy to change the sound, harder to improve it for long term satisfaction. Well, I haven't said anything new. Best of luck!

Well, BDR MK4 cones do not shift tonal balance. They are as neutral as it gets. However the MK3 stuff are colored.

Well, some like it neutral and some like it colored. I go strongly for the MK4. Decisions are up to you.

I have the Neuance shelving, but have not yet installed it. There are user reviews of the product at this site in the "shelf" and "isolation" threads. I am hoping to completely eliminate the use of cones and footers so that my equipment can rest on a solid and secure base (on stock feet). The weight of power cords should also have much less of an effect with this type of setup which is a definite plus. My shelves, though custom in that they have 8 sides (instead of 4) were quite a bit less than many of the other support systems. I hope to have them up and running in the next couple of weeks. Anyway, it's another way to go.

Don't mess with all the cones, roller balls, and other BS.
I built magnetic levitation pods and they kick ass! The only contact with earth (besides a small amount of side pressure) would be from the cables that connect to the cd player. This kills nearly ALL earth born vibrations!! The sound is improved in the following ways: Bass is deeper and cleaner. Soundstage is much more airer. The music just sounds so much more REAL when you can "float" the cd player or transport above the shelf. All materials can be bought locally. See my instructions on the PS Audio web site and happy building!!
