Shunyata Research Sigma v2 Speaker Cable

Sigma Series cables showcase technological innovation and design execution that simply does not exist elsewhere — at any price. Sigma Series cables combine meaningful parts innovations with objective measurement and an artisan’s eye for construction quality. Unlike many cost-no-object cable products that have little in the way of discernible science, Sigma Series products incorporate an array of definable technologies that set the standard for quality and performance in the cable industry.   Shunyata Research’s Sigma Series is quite simply our highest-performing speaker cable. Exclusive HARP technology reduces current resonances within the cable while ΞTRON® technology eliminates dielectric absorption distortion. KPIP™ eliminates burn-in issues.   ΞTRON® is a technology developed by Shunyata Research that prevents dielectric absorption and re-radiation in signal transmission. It requires a special type of conductor that has two signal paths and an electric field compensation circuit
