No longer have Cary's, but FWIW...
I am evaluating 2 power cords from Tek Line Cables. The microReference is $350, the mRXtreme is <$700. THese I just got yesterday and have no definitive statements other than it sounds terrific on my PAysonic 168 CD player.
The mRefs are great value, providing me with a large sound stage. Also impressive is the music's ebb and flow. Wood instruments, like pianoo, cello, upright bass have a naturalness and rightness about them. In my system I can hear the cavity resonance. In classical/big band the location of instrument sections and the separation within them provides a better connection to the music.
