looking for best isolation platform for CD player

Sean or anyone, what do you think about magnetic levitation feet? So the the component is suspended with no contact at all?
Rollerblocks seem to be good at both isolation and vibration transmission.

What i find interesting is that Tom and Warren seem adamant in their support for their beliefs. Nothing wrong with that and i agree that products and companies that are well designed and have been a pleasure to work with deserve support and recognition. I do think that there is a problem in that both of these folks ( Tom moreso than Warren ) tend to disregard other approaches, even if they know nothing about them. They do this even though some of those other approaches ARE taking measurements and have verifiable proof that their design works AND works quite efficiently.

As a side note, a device that reduces measured vibration does so on a whole, not just on the initial point of excitation. This means that both initial excitation and ringing are reduced on a well designed product. As such, a device that suffers from "stored energy" may reduce the initial amplitude of resonance but it does so by spreading the energy out over a wider period of time / phase. This is not an improvement so much as it is a lateral or even possibly backwards move. The end result would be dulled transients ( lack of dynamic impact ) and a reduction in overall clarity and definition (due to un-natural decay characteristics as a result of massive ringing ). This is exactly what i experienced with the MGD Deluxe Just-A-Rack.

With the above in mind, i think that most "damping" or "isolation" devices on the market fall into the category that Tom and Warren are "complaining" about. Not only are most of them under-designed on the whole, they are not optimized for any specific component or situation. Given that Joe's approach seems to be relatively well thought out AND optimized for each component that it is used with, it seems only natural to achieve better results with it than with mass produced "generic" devices trying to achieve similar results. I don't think that anyone here doubts that a "one size fits all" type of device will typically be "slaughtered" by a custom built piece that is quite specific to the situation at hand.

Other than that, i have to admit that i have not personally used these devices and have no first hand experience with them. I am basing my thoughts on science being applied to the art of resonance control. Sean

PS... I just picked up an accelerometer today and hope to do some testing in the near future.

Again there is no such thing as isolation. Dampening is another storage medium with uncontrolled time release of stored energy back into the devices on it, under it, and within it. Dampening is not selective upon the frequency nor the amplitude at which it covers... What about the natural dynamics with in the bandwidth that is to be damped? I have been around many moons. Coupling floats my boat!!! The direct path is the best path and shortest way to get there. Removing all the rubber material on all my chassis's is to me further audible proof that coupling is the best way to get there..Has anyone on this thread other than Warren tried direct coupling and resonant energy transfer? I for one have tried many so called dampening/isolation racks and even wall treatments, all were relegated to the used file or the giveaway file. Direct coupling all my mechanical devices has increased the reality of my listening experience..

Levitation cannot isolate a component from airborne sonic attacks. Neither the self generated internal energy nor the airborne disturbances are provided a point of relief. All of this trapped energy will be reamplified. Tom

Anyone toying around with the idea of coupling? Does some of this make sense on paper? Hearing is believing, right? Get on the Starsound Technologies website if you dare. Read some of the white paper. Then, order yourself a platform. Just one for your cdp. Maybe two? Speak to Robert, first hand. He be da man over there. Smart, audio savvy, patient, low key and very patient. They have a FULL money back guarentee. Whattaya gots to lose? I was convinced. I'm coupled now. Hearing is always the deal. All you audiophoolish potential couplers know your systems intimately. Who better then yourselves, to hear if this coupling (jive?) is what Tom and I have been raving about. Try it. You'll thank us later. peace, warren
