ac cables falling out of IEC inlets on amps

Tvad- I've tried tape with only partial success. It seems the inlet is slightly tapered, so taping Marinco connector prevents full insertion.
Kenscollick- Your tip of bending the contacts might have some merit. My incentives for replacing the IEC include thr understandin that some are spring loaded and exert a thght grip. Also, I am attracted to the idea of moving up in quality, if it would improve the sound of my system.
Thanks, pummy

Fatparrot-
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.
