Audioblazer I also have a cj350 and I use a PS Audio Statement Xtreme power cord. It has a 15 amp IEC so I use a 20IEC to 15IEC connector from voodoo audio (bought here on the Gon). I am using a 20 amp circuit to the amp with PS Audio Power Port recepticle (accepts 20 amps). Not sure this answers your question. Neither cj nor PS Audio felt there would be any issues with what I was doing. PS Audio didn't offer a pure 20 amp IEC end on their power cords at the time; don't know if they do now or not. PS Audio also commented that there would be no issues with connecting there power cord to a 20 amp circuit.
