ac cables falling out of IEC inlets on amps

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.

How are you applying the blutack to the inlet?

I would imagine that Blutack isn't conductive, because if it is, you could encounter a nasty short. I'm also curious as to how you would apply this stuff inside the iec of the amp. Is this the stuff?

Arthursmuck and Sherod- I'm applying it as a small ring on the Marinco connector,where it will contact the inlet only in the area furthest from the inlet's prongs, where I certainly don't want it to reach.
I have now installed it on the connectors for my SACD/cd and preamp, in addition to my monoblocks. The jury is still out, as the effect is not nearly as dramatic as when I used it to tweak my monoblocks. After I've lived with it for a while, I'll have a better sense of it. In any case , doing the monoblocks was very worthwhile
Sherod- Yes, this is the stuff. Except, I paid $3.29 for it at a local merchant.
