In my personal experience, the Epiphany X is an excellent power cord for source applications, pre-amps, and line conditioners (including the Sound Application RLS).
In regards to amplifiers, I have been satisfied with the Nordost Valhalla cord. Another cord to consider is Zcable's Cyclone (with a length of six feet or longer).
