I sell a lot of Audioquest cables. I love them, but there powercables are not in the same league as the other cables they make. They are ok, but not stunning. Purist Audio makes better powercables. We compared them with Audioquest. They were superior. Shunyata gives a deep and wide stage but misses the sharp small individual focus of instruments and voices. The Purist Audio does this part a lot better. Also the mid freq. of the Purist are more open than the Shunyata powercables. Purist Audio is one of the best brand in powercables or even maybe the best!!
