Sigma USB cables feature Precision Matched Z conductors. Signal and power wires are heavily shielded for superior noise immunity. Each Sigma USB cable is handmade. 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 that is sonically analogous to the use of diffusion panels to treat frequency irregularities in room acoustics. ~ Patents Pending ~
