Cones/Bearings for CD player

After trying quite a few, the PolyCrystal has had the most dramatic improvement. If you really want the best, the Aurios MIB's are collecting a lot of attention on that level. It is the bearing that stabilizes electron microscopes. http://www.mediaacc.com/accessories/aurios.html. But it doesn't come cheap, $300 for three. You could buy a lot of PolyCrystals or Black Diamonds for that. There are also the Bright Star Audio air inflation platforms that start at $100. No charge for the indecisiveness.

Black Diamond Racing Cones is the way to go. I tried them under everything and works like a charm. It's really CHEAP for the improvement you get. Additional improvements can be obtained by using the cones with the pucks they sell. Although the pucks costs more, the improvement you get is unbelievable!

Also better yet, available in 2 flavours!

i have yet to hear any sonic improvement from my cd transport or dac with any aftermarket product, save powercords and a zoethecus stand. my purely personal view: don't expect any miracles for $30, or even $300, if you're putin' your cash solely into isolation devices. -kelly

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!
