After using dozens of high end power cords over the years, I have concluded that the NBS cables are among my favorites. Used, they represent a bargain for quietness and sheer natural performance. This is the Master model power cord. It was purchased as a 1 owner from the Paragon of Sight and Sound in Ann Arbor Michigan. It is 6 ft. long with a 15 amp iec connector. There is a corner piece of the shrink wrap missing from the iec connector. It does NOT in any way harm the integrity of the connector, or the performance. Music lovers who use the NBS products seldom switch. I guarantee its authenticity. First Class USPS shipping is FREE! This auction is for the USA only! Paypal fees are included as always. I encourage you to check my reputation on Ebay as well. 100% perfect Feedback score of 1400+. Same User name. =================NOTE============================= I was told by the dealer that this is a Mark 3 model. It only says "Master" on the cable.
