I've had very good success with the Zu Audio cables. Most of my Zu cables are the Bok power cord. They are very good at lowering the noise floor and improving the soundstage, plus vocals and acoustic instruments sound more natural. I had always been curious about the Zu Mother but hesitated because the reviewer cautioned that the difference bewteen the two cables were subtle. However exhcanges with other Audiogoners indicated that the difference between the two cable was not as subtle as the reviewer suggested. I took the plunge and just bought a Zu Mother power cord and it exceeded my expectations! They do everything the Bok does but just better and not marginally so. Now I'm hot to trot to replace all of my Bok power cords with Mothers. Happy listening.
