Component isolation

Thank you Geoffkait for your informed observation,for sure you are certainly right...I will be more cautious in my explanations and think more in term of piezoelectricity...The effect is so audibly evident that I had looked for the beginning of an explanation...

geoffkait14,385 posts03-20-2019 6:54amNot sure I go along with your detective work. Radio frequencies, like light, are not affected by magnetic materials or by charged materials. Photons, which comprise radio frequencies, have no charge. So, crystals by themselves or “charged crystals” would not make them RFI/EMI attractors or absorbers.

I did Geoffkait yes...Thanks for your generous answer and tip...

geoffkait14,365 posts03-19-2019 6:38amReverse piezoelectric effect is probably the operating principle.

Thanks Geoffkait… This is food for my thinking...If I understand you the stones " filters" the EM of my interconnected audio gear by transforming a part of the distortion cause by the interactive EMF induced resonance in heat...Then  the stones placed along the main electrical line of my house act in the same manner: by piezo-electrical reverse effect? They "filters" by absorbing a portion of the electrical field and transforming  that into heat ? 

Thanks for your time I want to understand this effect, that was eyes opening for me with my audio hobby more than any purchase and more than any upgrade...

Ok ...Thanks for your observations,that makes sense...But You dont explain to me why stones connected with batteries+magnets act the way they act on the sound … I have experimented with that for the last year and the results are so great I am curious the reason why and you seems one of the few people who understand something about stones in audio...

Thanks very much GeoffKait...I appreciate your explanation and it seems to me very clear....

I use a grid of stones connected by cable and with many batteries+magnet nodes like a passive grid parallel to the normal audio grid(speakers+dac+amp) and the impact is astounding , do you have an explanation why this passive grid(stones+batteries+magnets) work?

Thanks Geoofkait for the clear explanation...But Geoff how my stones or crystals act on that loop? I sense that these stones "filtrates" in some way but I dont understand exactly how and why... Do you have an answer?

Any expansive vibration solution is certainly not worth it,because the money invest would be more useful at any other link of an audio system... I eliminate audible vibration at low cost in my system...


The greatest underestimated problem and more difficult to solve atlow cost is cleaning the electrical line and the audio line system...

All my audio gear,speakers included, are on my desk beside my computer screen...

There is the mechanical vibration and resonance problem I partially solved with my own device at low cost (quartz feet+granite plate+sorbothane+garnite plate+cork plate+bamboo plate+sorbothane) under my 2 speakers and under the dac and under the amp... I also damped the speakers with concrete slabs 60 pounds or more on top, with some little less slab on top of the dac and on top of the amp... i also glued sorbothane around the cone of the speakers and around the cups of my headphones to isolate the cups...The difference were very audible...The load and the quantities must be determined by listening, because like Michael Green said too much constrict the harmonics much less expand them...

But more importantly than mechanical vibrations and resonance was the noise floor threshold that is too high, in any audio system, if not taking care of +EMI interference of any part of the audio system with any electronic appliance in the house or the neighbourood... The solutions in the market are generally linked to the purchase of some power supply and conditioner or isolator from the computer noise etc...

Filtering the electrical line with active electronic components "clean" the sound but the price to pay is some kind of "reframing" the sound, because it is a trade-off between the component that are introduced that clean and the one to clean...The best solution for me was to use stones and crystals that are passive filtering device with no trade-off, because the floor threshold of the audio grid is not modified by the introduction of new electronical active components, then a net lowering of the total noise floor of the system follows... They are filtering passively... The upgrading effect on the audio line and on the general electrical line of the house was so astounding that nothing I purchase compared to that...The same gear I was not totally satisfied with are now so good that a "real" upgrading is impossible really under 25 thousand dollars … My system net cost is 1000 dollars... And you know what, even if I had this money I am not certain that I would buy that 25 thousand bucks new system,because when you are happy with the music for the first time in your life, you dont feel the need to upgrade...My system is not perfect, but for the price modulo these cleaning methods it is unbeatable...


I read so many forums about audio, I know that most people underestimated completely the vibrations problems, but more than that the most important problem linked with the electro magnetic and radio interference between components equipment from the room, from the house or the neighbourhood.....
