One of the finest power cords designed specifically for digital gear (up to 60 watts) that money can buy.  This cord incorporates an active (battery-powered) shield designed to isolate system noise from the system ground and reduce coupling capacitance. 

"Hints of warmth and superb bass extension ably underscore the effortless bloom and roomy soundstage performance of this power cord."  Neil Gader, The Absolute Sound 
 
"The performance of the Challenger is not subtle or restrained.  With the shield active or not, the Challenger challenges any power cord I know of under $5,000..."  Robert Levi, Positive Feedback 

"...the Challenger is one of the best power cords for digital components."   Marshall Nack, Positive Feedback

Editor's Choice, 2015 The Absolute Sound
 
This 1.5-meter power cord is in very good condition and comes with its dual AA battery pack to power the Dynamic Shield.  At my asking price, PayPal fees and shipping to U.S. and Canada will be included. 

Questions for the seller
D to A convertors, or DACs have an analog section as well as their digital section. Can you tell if the Challenger has a benefit to the analog section ? Have you tried the cord on an analog component such as a preamp or headphone amp ?
All components, including both digital and analog gear, benefit from reduction of RF noise, and so both the digital and analog side of a DAC will benefit from the Challenger AE15. The limitation of the Challenger with analog gear such as amps would be that its shielding circuitry is ineffective beyond 60 watts. I confirmed this with the manufacturer. So with just about all preamps, this is a great solution. With many headphone amps, it can work just fine but I would personally verify that the amp isn't drawing more than 60 watts during certain peaks.
