Know before you buy
No, it does not. The cable undergoes Shunyata's proprietary KPIP (Kinetic Phase Inversion Process) during manufacturing, which significantly minimizes the typical burn-in time required for high-end audio cables.
TAP, or Transverse Axial Polarizer, is a patent-pending technology designed to preserve critical signal timing. By maintaining the integrity of the signal's timing, it helps the cable reproduce audio with greater clarity and a more natural, analog-like sound.
Yes, the Sigma Series USB cable is built to the USB 2.0 standard, making it fully compatible with standard USB-A to USB-B connections found on most high-end DACs and audio streamers.
The 100% coverage silver-braided shield is essential for blocking external electromagnetic interference. By effectively isolating the signal from noise, it allows the cable to achieve an ultra-low noise floor, revealing finer details in your music.
Precision Matched Z conductors are engineered to ensure consistent impedance across the length of the cable. This precision helps reduce cable-induced jitter, resulting in a cleaner, more accurate data transfer between your source and your DAC.
