I dare say you can not post a "review" of power cords. Every one that I have tried sounds different using different components...in fact, I am using my favorite cords which are Furutech connections on Accrolink, and Oyeida ends on Accrolink. I have an all Ayre system, and tried the Furutech on the amp and also on the preamp. Furutech sounds different on each of these components as do Oyeida. It was easy to hear that the amp liked the Furutech and the oyeida less so, with the preamp and Universal player liking the Oyeida, with the Furutech less so. In my system, any of the Cardas cables sound dreadful..though other systems may prosper from them. Nordost, Purist, Kabula, etc all sound different...not as good in my system, but may very well sound great using other components...one never knows until you use them in your own system.
