I believe that most digital source cords just have a lower current rating than amplifier power cords. In the past, I've used a Van den Hull hybrid PC (amp cord) on my DAC without a problem. The Van den Hull lists for around $425 but can be found on audiogon for $100-$125. I now use it on my amp and a K-works PC on my DAC. The K-works empowered cord is superb on either the source or amp. In my opinion you will have to spend an insane amount more to get better cords.
