Looking for feedback on the merits , tonal signatures of the Shunyata Anaconda Zitron and the Purist Canorus . Has anybody heard or better still tried these cords in their rigs . They are both Copper conductors and retail for around the same, so feed back would be appreciated . Also if there a link explaining what the Zitron tech actually is . The Shunyata site seems a tad under-done .
