Has anyone tried these SnugPlugs?

Furutech GTX-D Rhodium outlet or Cardas 4181US Duplex Power Outlet are way to go. Lot's of these fora too.

I replaced my AC outlets with medical grade outlets and they hold great. I would like to find something to snug up my IEC connections. I have 2-3 that are jiggley and I’d definitely like to tighten them up.

Sounds like another 1/2 way gimmick, God knows audio has enough of them. Take the hospital grade advice.. will still give you full contact, +solving the jiggle problem. Don’t worry about any of the burn in BS or high dollar supposedly audio specific outlets, do worry about diminishing returns.

Interesting idea, but my guess is that for most "loose" outlets, the Snug Plug would make it difficult to fit an audiophile plug once they were inserted into the outlet.

That being said, I wish I would have thought of it. 

If you notice, there’s Vaseline in the outlet to ‘demonstrate’ the loose plug. 99.9% of outlets don’t loose the plug to that extreme. If it does, replace it. Use a hospital grade outlet and save your $$ on the audiophile type.
