MRI grade vs Hospital grade electric outlets

magnetism in the outlet will not affect your SQ

the only thing you need from an outlet is good contact so your amp will have adequate current flow esp. on peaks and there is no need to spend more than a few bucks on an outlet -- if that

save up for some Wilson speakers or Reveles or big Maggies, etc.

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
