hospital grade or commercial grade receptacles ?


What is the difference ? Is it really worth ten times the price to get hospital grade receptacles ? Why ?
Is one brand really superior to another? Is Pass &
Seymore a good brand ? Hubble better ?
I am setting up a closet to house my mid-fi gear and
will be running two dedicated 20A. lines to run the
2-channel audio and the home entertainment equipment. I
will have two double (2 duplex receptacles) on each 20A
circuit.
Thank you in advance.

I void to never again add to this useless thread, but Irvrobinson's last post saying, "If someone will send me at least one cryo'd cable I'll give it a listen." is the ultimate in hubris. He thinks he is the authority!
Irvrobinson,

That machine we are both "pecking" on is partially the development of Texas Instruments, of which several of their key people are friends of mine. I have been doing photography for them for nearly 20 years.

Here is the fuel cell press release for Jack Harrod, an avid audiophile and another person suffering from hallucinations of purchasing Purist power cables.

Jack lives in a multimillion dollar home with original art work, including one Pablo Picasso. He has a fabulous sound system. Likely one you would not approve of because it is all tube and has high end cable throughout.

Between Jack and our Grammy award winning musician, we have some real catching up to do to equal our resident Physics genus.

By the way, Jack tried to use a volt-ohm meter to verify the quality of the Picasso. It did not read 100 on the meter so we are now afraid to enjoy it for fear we have been duped.

His system is used to edit the discs for sale at your local music store. He
toopurchased Purist cable throughout. But hey, what does he know? A degree
from Juilliard can't possibly qualify him to know what sounds good. A Physics
degree is required for that.

Very cool. I love his Mahler: Symphony No. 2 "Resurrection" on Delos SACD.

I'm keeping my physics/applied maths honours degree under my hat, and my Bob Crump (TG Audio) power cords in my system.
