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.

Eldartford, that explanation is a fraction of what occurs when electricity passes through wire. In fact, I think next to proper gauge for the conductor, possibly the most important thing is the insulation.

Insulation can store energy and release it in non linear ways and various layers between the conductor (and outer jacket we see) can have a huge effect on sound.

A perfect example is Purist Audio power cables, which I am so fond of. The conductor is approximately 10 gauge and constructed with a mix of metals that have proven to provide excellent results.

My argument is NOT that Purist Audio's mix of metals is so proprietary that Audioquest or Shunyata (or whoever) cannot duplicate it, but rather the shielding, grounding and isolation from vibration, EMI and RF are of equal or greater importance.

Most of the time plugging in such a cable results in a blacker background with a more relaxed presentation and improved textures and resolution.

To understand this, you need to view the power cable as PART OF THE POWER SUPPLY rather than an extension of the Romex in the wall.

If you assume your AC power is perfect and your power supply in your stereo gear is immune to EVERY POSSIBLE contamination, then possibly the power cord will have less effect. However, there is still the issue of vibration.

For that reason, there is more than one audiophile manufacturer that addresses that problem in the construction of their power cables.

The energy drawn through the wires moves the wire vibrating it. A perfect example is caused by strobe lighting used in my photo business. The capacitors in the power packs sometimes causes the walls of buildings to "talk" back every time a burst of energy is drawn.

This power draw through the conduit is powerful enough to "bang" the conduit against the wall. I have had this happen hundreds of times over the last 30 years, even in high rise commercial properties.

In the last ten years I have seen almost no situations where a premium power cord did not help the equipment it was plugged into. Differences in design from manufacturer certainly provide an array of results, some of which I find desirable and some I do not.

To say that they effect in no way is absurd. In fact I hear differences between different brands of male wall plugs. Most often this manifests itself as tonal balance changes but sometimes as distortion. I assume this has to do with conductivity, vibration, and clamping action.

It's all important and cannot be measured with a volt ohm meter or resistance specifications.
first.excuse my grammar because english is not my natural language,but after going through this thread,i couldnt help myself but to jump in and sharea little of my own opinion.I am an EE for HP for the last 15 yrs designing hi-end server micro-processor.i do have my MS in EE,so i do know a bit about electrical signal.when i first start out this hobby,i think it crazy when people can hear the difference in cable and IC,because on theory ,there is no difference,but i have an openmind to keep trying out all diff cables to see if my ear can pick up the differences.Now,3 years has gone by and i still cant hear the difference,but i do not doubt any one who can,because there are more then just a few that swear that they can.I dont think those people are stupid enough to spend thousand of dollars on something that they cant tell the different.what i am trying to say for mr IRV and Eldartford is,comming from the same electronic background like you two,i understand where you are comming from,but dont you think there might be 1 day that technology will come up with something that might be able to measure the differences in cables that only certain person with gifted hearing to pick up those signals??..just my opinion.
