  • What is CRYO?

    Cryotherapy is the use of extreme cold applying on the metal of the cable. This technology allows your cable to be upgraded by enhancing conductivity, erasing interference, and re-arranging the metal particles in order.

    Your cable will bring to your system more clarity, more detail, less background noises, and better music listening.

  • What is QBT?

    Quantum Burning Technology applies a similar but reverse polarity frequency against noise, so the noise will be cancelled out. It may takes a longer run-in time than cables without QBT treatment. But the benefits of it is permanant.

    Your cables will bring to your system better position of the sounds, better silhouette, and openness.
