Switch to a lighter cable, as well as replace your wall receptacle.
Be aware, even if you get a stronger wall receptacle, you can end up stripping the box itself.
If those cables weren't so pricey I'd suggest having the plugs replaced. Cardas does make some low profile, much lighter weight connectors:

Of course, not every device benefits from a pricey cable. Have you listened to them with consumer grade versions?
