Heavy Power Cords

I cut up cheap 7/16" thick foam work shop floor tiles and stack them horizontally for strong support under all my cables and especially the P/C's where they attach to the equipment.

Sort of like the other mention of it... I'd add some layers of heat shrink, one at a time until the fitting was snug.

Of course, that's not helping the contacts get tighter but will help the cords from pulling loose.... also, I use plain old string to trace up the heavier cords to the rack itself... thereby taking the strain off the connection.

Blindjim suggestion is similar to my own, I use Tiewraps to hold the AC cable in place so there is no strain on the connector.

Likely the same results as he gets with string.

+1 to Samhar.

I use anything I can find to support the connector from underneath so that it is level (i.e., pencil erasers). Have this problem especially with my small DAC and a 14g PC, but also with my big ONK 805 avr and a 12g PC.

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,
