Since 2023 we have been using a company in Peterborough, England to cryogenically treat our OCC silver and copper wires.
Here we give some general information about the process and the benefits.

Cryogenic Treatment
Cryogenic treatment is a specialized process used to enhance the properties of various materials, including wire, by subjecting them to extremely low temperatures. This process involves cooling the material to temperatures well below freezing (typically around -300°F or -184°C) and maintaining it at that temperature for an extended period, often several hours or even days. Here’s an overview of the process and its benefits for the audio cable industry:
Process of Cryogenic Treatment to Wire:
- Preparation: The wire is first prepared by ensuring it is clean and free of any contaminants that could interfere with the cryogenic treatment process. This may involve cleaning and degreasing the wire to achieve optimal results.
- Cryogenic Chamber: The prepared wire is then placed inside a specially designed cryogenic chamber. This chamber is capable of reaching and maintaining temperatures well below freezing for the duration of the treatment.
- Cooling Phase: The temperature inside the chamber is gradually lowered to the desired cryogenic temperature, typically over a period of several hours. Once the target temperature is reached, the wire is held at that temperature for a predetermined period, allowing the material to undergo structural changes.
- Warming Phase: After the allotted time at cryogenic temperatures, the wire is slowly warmed back to room temperature. This warming phase is often conducted gradually to prevent thermal shock and minimize the risk of any adverse effects on the material.
- Post-Treatment Processing: Depending on the specific application and desired outcomes, the wire may undergo additional processing steps following cryogenic treatment. This could include annealing or stress relieving to further enhance its properties.
Benefits for the Audio Cable Industry:
- Improved Electrical Properties: Cryogenic treatment can lead to improvements in the electrical conductivity and signal transmission properties of wire. The process helps to refine the microstructure of the material, reducing internal resistance and impedance, which can result in clearer and more detailed audio reproduction.
- Enhanced Durability: Cryogenic treatment can also increase the durability and longevity of wire by reducing internal stresses and strengthening the material’s structure. This can result in cables that are more resistant to bending, stretching, and other forms of mechanical stress, making them ideal for high-performance audio applications.
- Reduced Microphonics: Cryogenic treatment has been shown to reduce the microphonic effects in wire, which refers to the transmission of mechanical vibrations into electrical signals. By stabilizing the material’s structure, cryogenic treatment can minimize the impact of external vibrations on the audio signal, resulting in cleaner and more accurate sound reproduction.
- Consistency and Reliability: Cryogenic treatment can help to standardize the properties of wire, ensuring consistency and reliability in manufacturing. This is particularly important in the audio cable industry, where uniformity of performance is essential for maintaining the integrity of audio signals across various components and systems.
- Audiophile-Grade Performance: For audiophiles and audio enthusiasts, cryogenically treated wire represents a premium option for achieving the highest levels of audio quality and fidelity. The subtle improvements in conductivity, durability, and signal transmission offered by cryogenic treatment can result in a more immersive and lifelike listening experience.
In summary, cryogenic treatment offers a range of benefits for the audio cable industry, including improved electrical properties, enhanced durability, reduced microphonics, and consistency in performance. By subjecting wire to extremely low temperatures, this process can help to optimize its structure and properties, resulting in cables that deliver exceptional audio quality and reliability
