MRI grade vs Hospital grade electric outlets


I know both have been suggested as an upgrade to the run of the mill cheap outlets. I also know there may be "even better" outlets.   I know the MRI grade has non magnetic metal components. Bottom line, does it make a difference one can hear? I have about 1/2 dozen Hubbell 30 Watt hospital grade outlets. Got them fairly inexpensively. Are the MRI grade worth the extra $$$?

ITS ELECTRICITY THAT COMES FROM AN OUTLET,NOT SOUND.
Contact pressure is the primary difference between good and bad outlets.
You can believe the hype,I'll put my money on more music buying, that's why I buy my equipment.

OR- a religion? Some must be experiencing Nirvana(literally means, "blown/blowing out", in Sanskrit).  Maybe Naive-ana?
Good Summary:
ITS ELECTRICITY THAT COMES FROM AN OUTLET,NOT SOUND.
Contact pressure is the primary difference between good and bad outlets.

- if you have really bad electrical power, then buy a transformer

- if you have ground loops then buy a Tripp-Lite or other good strip

- if you have a deep seated religious belief that defies the laws of electricity, then do a blinded test of the magical expensive outlets

or just rub snake oil on your outlets
