I've been told that my power cords (Harmonix XD-C Studio Master) is a tuned cord. Nothing about the "tuning" thing motivated me to buy these babies. The fact that a golden earred buddy of mine, traded in his Elrods for these, was enough incentive for me. They are absolutely amazing as is their Golden Performance IC, which may be tuned as well. Their website might offer more info about this. Me? Don't give a ______. It's the sound that matters. My tunes, certainly sound better with these cords and ICs. peace, warren
