I've actually rigged up a little sling for both my amp and phono stage, where the weight of the cord wants to pull it down. I just took some string and looped it around the shaft of the cord by the IEC plug. Then I twisted a metal clip to atach to some point on the top of each component and attached the string (I used a picture hanger, but you could probably use a paperclip or something similar). Of course you will have to adjust the string tension to get it right, so I advise using a slipknot.
Enjoy,
Bob
