Has anyone tried these SnugPlugs?

+++++++1 to just replace the receptacle. You will get a vice grip type connection, and superior audio performance. I've tried well over a dozen receptacles, and all improved the sound over a stock socket. Look around for prices, they can vary by as much as $50 per unit

I use (and can highly recommend): Furutech GTX-D(G or gold) $165, Furutech GTX-D(R or Rhodium) $180, Oyaide R1 (Not SWX series) $160, and for the more affordable range Acme Audio Labs (Silver, cryo'd, CFC coated) $75

Dear lord, no.

If your plugs are that loose they need to be replaced. The NEC now requires tamper resistant outlets in most outlets in the home, so not even sure a snug plug would work in any outlet that’s compliant.

A decent "commercial/residential" outlet runs under $5. These are commercial grade outlets with tamper resistance also I think. Check Lowes or HD for bulk deals (10 in a box).

If you still have a loose after replacing your outlet get a hospital grade plug like this one from Leviton which also saves you on floor space. The extra thick prongs and ground pin make them grip much better.

Next, if your outlet wiggles in the receptacle use spacers like these or these to make sure your outlet is rock solid.

One of the biggest reasons for replacing the outlets is also to check for backs stabbed connections which are dangerous and prone to failure. They have tiny little prongs which grip up to 14 gauge wire. Worth removing and side wiring or back wiring. Back wiring still uses a screw and clamp mechanism.

In my listening room I have a daisy chained circuit which is mostly isolated, but daisy chained back stabbed outlets are definitely worth removing.

Everyone,

Thanks for your inputs.

After the many "don't do it" comments, I will have the loose outlets replaced.
