The power plug on the X-1000 isn't all that special. It is a 20 amp IEC vs the 15 amp IEC found on most High End audio products. My X-600's were ordered with the X-1000 input boards complete with the 20 amp IEC's. All I had to do was change my wall sockets to 20 amp units.

Has anyone ever heard these amps in a 2-channel system?
