ac cables falling out of IEC inlets on amps


I use medium weight power cables with Marinco connectors.They sound good, but they fit in the IEC inlets on my monoblocks only loosely and can easily loose their connection. I am considering replacing the inlets on the amps with ones that solidly grip the powercord.
Any suggestions?

I take it you have tried blutack and it worked out well for you, and you tried some other brand and it didn't. Can you say a little more about your experience?

this is amazing as I just sent my mono block amps off because of this problem...
Fatparrot-
I tried your suggetion with regard to Blutack. To say it worked seems, at this time, an understatement. The connectors are staying in place, and there is a remarkable effect on the sound.The image has enlarged, become more specific, and noticably more transparent.
No doubt part of the positive result simply stems from a more solid connection, but I would guess part of it has to do with the vibration damping effect of the Blutack. You may have found a significant tweak here. I'll try it on the IECs on my SACD player and preamp. If it works out, I'll let you know.
