TAP reduces electromagnetic polarization distortion. Sigma digital cables are constructed using Precision Matched Z to reduce jitter and signal reflections. Expensive fluorocarbon dielectrics and impedance matched RCA connectors ensure reference performance. KPIP eliminates burn-in issues. As the performance vanguard in the Shunyata Research's cable line-up; Sigma Series cables take the term 'state-of-the-art' to an entirely new level with the introduction of two new cutting-edge technologies. The first, integrated in the Sigma Series interconnects and digital cables, is the 'Transverse Axial Polarizer' (TAP). It minimizes a form of 'micro-distortion' identified as 'electromagnetic polarization' that reduces 'sonic glare' while increasing clarity and coherency. The second technology incorporates a proprietary device called HARP that reduces current resonances within speaker cables – a concept somewhat analogous to the use of diffusion panels to treat frequency irregularities in room acoustics.
“Sigma reduces noise, glare, and apparent time smear to levels that allow more of music’s appeal to come through better than with any similarly priced cables I know of—and by a shockingly wide margin.”
