I plan on changing my outlets since it seems like a cheap enough tweak and most here on the forum agree that it makes a difference. But what actually IS the physical difference between hospital grade and non-hospital grade outlets?

It's Contact Pressure......You misssed the whole point. ============
Nerspellsner, LOL, I never heard of that test, LOL. You do know there is a device that plugs into the outlet and while extracting it, will give you the resistance to the pulling action in ounces... Jim
Jea48, I have heard of that device but I have never used it. I remember hearing that the device is connected to the ground pin only. It has to stay connected to a hospital grade outlet with 4 oz of pressure for a certain amount of time. I concur with your statement about removing a plug under a load from an outlet will cause an arc, regardless of the type of outlet.
All outlets get looser as stuff is plugged in and out many times. A "pull test" is a practical way for the maintenance staff to determine how far the degradation has gone, and when it is time to replace the outlet. Wearout should not be a concern for audio applications since it does not involve frequent plug/unplug cycles.
