Sigma AES/EBU interconnects feature Shunyata Research's exclusive patent-pending TAP Polarizer technology. TAP reduces electromagnetic polarization distortion. ZiTron technology, Ohno Continuous Cast Copper, VTX (hollow core) conductors with expensive fluorocarbon dielectrics make for a true reference quality interconnect. 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.
"By removing so much noise and interference from the path, Shunyata's flagship cables renewed my passion for recordings I'd begun to take for granted."
