Many JENA LABS wire products are Deep Immersion Cryogenically treated as part of the standard production process. Those for which Cryogenic treatment is not standard may be ordered with optional Deep Immersion Cryogenic treatment. This treatment entails a cold chilling process culminating in immersion of the cables in Liquid Nitrogen, also known as LN2. The boiling point of LN2 is -320.4° Fahrenheit, [-195.77° Celsius] or about 400° F below warm room temperature. In the liquid state as we use it, the LN2 is actually much colder than this temperature.
Exposing metallic objects to this extreme cold causes beneficial molecular changes to occur. As metallic objects cool, they shrink. With the extreme cooling and the shrinkage that follows in LN2 immersion, the crystal boundaries of metallic conductors align more closely with one another and become more conductive and quieter. Mechanical integrity is also improved. The improved molecular condition stays intact through the slow warming process and is stable at room temperature.
When conducting an electric signal, treated wire and formed metallic parts will produce less micro-diode-effect noise, less impurity inclusion field disturbance and less 'slow field' transverse energy generation. The result is a cable or electrical device that is quieter in noise floor and more revealing of subtle musical nuances.
Working with LN2 requires very specialized and expensive equipment, and extreme care in process. It is very dangerous, as the cold is so severe that it can result in severe injury from accidental exposure to the liquid. The process of chilling and warming takes several days to complete, and if done incorrectly can result in the fracture and loss of the materials being processed. In every phase of the treatment, extreme care must be taken. We feel strongly enough about the musical merits of the treatment, that we gladly make the investment in the equipment, the time, and the safety procedures needed to make the benefits available to our customers.
CDs, SACDs, and DVDs
Optical discs used in home entertainment benefit from Cryogenic treatment. The sound produced by treated discs is smoother and less fatiguing, while also bringing a sense of wider frequency response, more dynamics and a much more life like detailed 3-D soundstage. The video portion of DVD information is improved with better color saturation, lower noise, and improved sharpness. JENA LABS employs a stirred Evaporated LN2 vapor system to treat optical discs. This treatment chills the discs to -320° Fahrenheit, which though not as cold as our Deep Immersion process, certainly qualifies as authentic Cryogenic treatment. Our experiments have shown that exposing optical discs to the extreme cold of the Deep Immersion process may cause some discs to fail. The stirred Evaporated LN2 Cryogenic process we employ is perfectly safe for the discs, and cold enough to impart the beneficial sonic and visual improvements we desire.
Beware of others Cryo-Claims
Several audio writers, equipment modifiers, and so-called technologists have promoted refrigeration of cables and electronic parts by packing in Dry Ice. This is NOT cryogenic treatment. It results in only minor and temporary improvement. Even gas bath refrigeration in a cold furnace cooled by LN2 will not provide a sufficient chill. Scientifically speaking, Cryogenics refer ONLY to temperatures at or below the vapor point on Nitrogen, -320.4° Fahrenheit. Our process involves temperatures that are substantially colder than this. Clearly, dry ice has nothing to do with Cryogenics. Only true Liquid Nitrogen Immersion, as employed by JENA LABS will fully and permanently enhance the musical behavior of metallic conductors.
