Electronics Detail

Cryogenic processing has some interesting effects on electronics and on stereo equipment. At this point, we are not quite sure why. However, what we are seeing is real. This is backed by the fact that cryogenic temperatures can modify crystal defects such as vacancies. As stated in the book STRUCTURE-PROPERTY RELATIONS IN NONFERROUS METALS, "Vacancies are of interest to designers of microprocessors because they cause current noise...in the thin metal films used in such devices." This and other effects are cause enough to know that cryogenic processing can and does change electronics.

Tests by major companies found advantages. Tests done by Boeing/Sunstrand demonstrated cryogenic processing extended the life of circuit boards in military applications, specifically boards used in cruise missiles. Tests done by Honeywell on experimental thin film magnetic memory wafers showed increased conductivity of metallic layers, reduced residual stress between layers, and possible (but not fully confirmed) "healing" of vacancies in the layers.


Tests on transformers showed treated transformers had significantly less hysterisis. The magnetic core saturated less. Tests on transistors showed a decrease in rise time. Other tests indicate greatly increased contact life on relays, switches, and circuit breakers. A paper done by San Jose State University in conjuction with Nortern Illinois University demonstrated that "Cryogenic processing has been proven to be efficient in increasing Schottky contact barrier height, and significantly reducing device reverse leakage current."

Cryogenic processing of audio equipment has been shown in numerous blind tests to improve the quality of sound in virtually all audio equipment and audio equipment components. 

How do we know this?

People in the business of building custom stereo equipment regularly send us components to be treated. When this started, we felt that this must be some sort of very subtle effect, that would only be heard by "expert" listeners, so we more or less treated their parts and didn't push things. Our conversations with these customers left us skeptical that the "ordinary person" would be able to discern a difference. Then something happened to change our mind.


CTP President Rick Diekman was invited to a meeting of the Chicago Audio Society (www.chicagoaudio.org) to listen to the difference between treated and untreated components. Its not that Rick doesn't like good music, he really does. But he figured that after years of being around noisy industrial environments, racing engines, and aircraft engines that the subtle changes he was anticipating would be lost on him. Was he surprised!

The society put together a medium priced system and played several selections on it. They then changed one component and played the same selections. There was an audience of around thirty people and the audience unanimously decided the second playing was far superior to the first. It was then revealed that the second playing used a cryogenically treated component. This was done over and over with different components being substituted. In every case but one there was a unanimous decision as to which component sounded better and in every case it turned out to be the cryogenically treated component. In one case, one person voted for what turned out to be the non treated component. 

The point is this. The treated components were virtually universally accepted as being superior in sound reproduction. Even Rick was able to tell the difference. As one person put it, this was a very inexpensive way to upgrade a system. 

Here is the testimonial from another user:

"I purchased new speaker wires which I wasn't sure I was going to keep. The imaging was sharp, the sound was clear and transparent, but the wires lacked weight and warmth. Then I had them treated cryogenically at Controlled Thermal Processing. As stereo lovers know, tweaking a sound system typically requires sacrificing one element or characteristic to gain another, yet, whatever I sent to Controlled Thermal Processing, I always get in return noticeable, even great gains in performance without any loss. After cryogenic treatment, my new wires have retained all the sharpness, and clarity, but now the sound has the weight and warmth that had been missing, as well as a feeling of power and impact I have never heard before from my system."
