If the cord fits the socket, it is safe. A standard C-13/C-14 cord is rated at up to 15-amps when plugged into a 120 volt outlet -- matters not if it is hooked up to an amplifier, CD player or computer.
CAN YOU OVERPOWER A PIECE OF EQUIPMENT
Using a PS AUDIO Xstream Statement SC Power Cord on my vintage Marantz SA-8001 CD player ( as well as my JOB INT) - and have been told that that cord is designed for use with power amps, not other equipment: true? can/could I damage my CD player if I continue to use this cord into it?
