Cones/Bearings for CD player

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!!

Darrell: I read your project notes with great interest, but do not think that things would stay afloat during one of our CA earthquakes. Plus it only addresses vibration entering into the equipment and does not drain any off. I have had better results in my setup by doing both, though I am certain that your method is excellent for isolating the gear and might sound best on a unit with an outboard power supply that does not suffer much from internal vibraton.

Stay afloat during earthquakes?? I think I'd be more worried about getting killed by falling objects!!!! As far as draining off vibrations you're correct. The best way to completely isolate would be to float only the actual laser and motor spindle assembly. I'm working on that now with some super powerful tiny magnets. Check on the PS audio website from time to time as they are also interested in my idea.
