I tried some of these a good while back on some AC cords and RCA interconnects. On the power cords, despite my best efforts I couldn't tell any difference regardless of the cord or positioning. I see these built-in to a lot of SMPS cords (on the DC end), so perhaps there is some benefit with a DC signal (or maybe just SMPS-converted DC). On the interconnects, I thought I heard some difference depending on the cable, but it was pretty minor and if anything it wasn't an improvement -- seemed to take some sparkle and air out of the treble. A lot could be dependent on the geometry of the wire lay, and possibly the external noise level in the environment (RFI, EMI, etc). Certainly doesn't hurt anything to try them on the HP cable though.
