Shunyata Sigma NR 15 amp power chord in a 2.0 meter length. Excellent condition and purchased new 12/21/2017 from an authorized dealer. This is absolutely the best copper power chord I have heard. It adds weight and warmth to the system and yet retains high resolution. Additionally, it reduces the noise floor of whatever gear its powering. I'm selling to move up to a three times as expensive all silver chord. I have all the original packaging that came with the chord. Please check my feedback. Thanks for looking!
