looking for best isolation platform for CD player

Here are brass cones for $19.75:

If you are going with the transfer method I don't see how four little cones are going to effectively transfer vibrations out of the component. I would think four 3" diameter brass discs would be better. Meaning as much of the case of the component is in contact with the medium which is transferring the vibrations.
Sure four little cones may be the right concept but I don't see them are being the most effective solution. Well, if you can locate the vibration nodes of the component's case and put the cones at those nodes they could work. Stereophile had a good article on this and find where the nodes are. As usual, I can'd find it now. If anyone cares, I will try to find it.

I found an accelerometer for $35:
Stereophile is good for something
In first the February 1991 issue of Voice Coil, then the November issue (footnote 1), Editor Vance Dickason described a low-cost accelerometer made from a strip of the piezoelectric polymer PVDF (polyvinylidene fluoride) that enables impecunious engineers to get a more objective handle on cabinet problems. Costing just $35 plus shipping (footnote 2), the transducer consists of a 4" by 1" strip of PVDF attached to a small plastic block from which emerges a short pigtail of coaxial cable. The strip is securely taped to the surface to be analyzed; the output can be fed to any of the standard industry measurement systems.

Footnote 2: For further details on this low-cost, $35-plus-S&H, PVDF strip accelerometer, see "High Polymer Piezo Film in Electroacoustical Transducer Applications," AES Preprint 2308, presented at the 79th Audio Engineering Society Convention in New York in October 1985 by Jesse Klapholz.

Geometry matters...... a lot. Notice the dampening pads. They will... interfere... with the collection.... and transfer of resonant energy...Tom

Tom, you are again condemning something about which you know nothing! How can anyone believe anything you say based on these foolish assertions?

You have never seen Joe Lavrencik's Isolation System, nor have you studied his papers. Your comments make you look ignorant (at best) or biased against anything with which you are unfamiliar.

Isolation may be a new science, and this gentleman's products may lead the charge in a new direction, you don't know. This is as stupid as people ridiculing Thomas Edison's attempt to reproduce the human voice nearly 100 years ago because it had never been done before.

I don't question your enjoyment of "coupling" there is room for all opinions, some people even like Bose Acoustic Wave Machines. That doesn't mean though that 'coupling' is the only way, or even the best way.

Is the science of isolation never going to change or develop? Tom don't talk about things or about subjects of which you know nothing. You bring into question your own credibility, and add nothing to the conversation.

Check out the product and then weigh in.

Tbg, not sure what your basis of comparison was but I have found the Nimbus to be more effective at isolation than anything else, including some of the other products mentioned. It isolates in all planes down to about 0.5 Hz which is far better than some which only go down to 3 to 5 Hz, as microseismic vibration is the biggest culprit.
