Audiophile Grade Wall Receptacle

As a person who works for a utility (currently in Finance, but with enough time on network design/engineering), why? I just don’t get this...

Hospital grade, fine. Clamping ability is great. If $20 makes you sleep better at night, so be it. The contact area of a 12/2 or 14/2 cable is your limiting factor, inside the outlet.

Add to that the clamping area of your neutral and hot on your breakers (smaller) and you’re looking at a choke point there. Most modern boxes aren’t rich in copper from the main to the buss legs. Your neutral and ground are commonly aluminum.

Service entry wire? Is almost entirely aluminum in the states since the 80s (I’m running utilities to my pole barn/pool house on Monday. It’s fed with aluminum, too.)

Show me on an OScope or with a good anechoic chamber measureable sonic changes, I’ll show you a corroded outlet or power cord.

I run $4 Leviton premium outlets from a local supply store. They’ve fed everything from the $120 Sherwood integrated I had in HS to the Gryphon I sold a few years back to the 452 I’m listening to now... Even if I change circuits to a non-home runned, noisy 15a, on a circuit the amp shares with other stuff, a well designated power supply filters it out.

Spend the money on a new LP or new cartridge. Buy the $15 hospital grade outlet and move on. If you want to bring your outlet over to my office, we can dust off seven figures of metering equipment; if bet the farm that any 20A outlet fresh out of the box will sound identical...

My advice? Get something UL listed from a major company (Leviton, Legrand, etc.) with solid quality controls and a good reputation. I’d bank on solid EE principles over smoke and mirrors anyday.

Current is current. If it’s rated greater than your amp needs, you’re fine.

I went to Albert Porter's site and there's no mention of any outlets anymore.
Oh well, at least we got ours.

All the best,

@audition__audio   I wasn't trying to be sarcastic.  I'm meant what I said.  If the improvment in sound is as great as the many, many posters suggest, then I should be able to hear it.  Still no one is addressing the elephant in the room.  HOW does a wall plug improve the sound when it resides well in front of all the other equipment.  HOW does Rhodium alter a sound wave?  HOW does gold plating give the music a warmer tone? HOW does any plug increase the bass?  Heck, I want to be a believer, but I'd like someone to explain HOW this is possible.  I'm running a Hegel H590, Parasouond JC3+ phono pre, Rega P8, Acoustic Zen Crescendo Mark ll, all premium cables.  

Several friends and I use Synergistic Research duplexes.   I prefer the blue, my friends have red and black (earlier/different) duplexes.  I know that they consist of commercial/industrial grade and relatively inexpensive outlets.  They are processed by SR as they say, with a million volts, either once or repeatedly to linearize the metal materials inside and coat them with a substance that includes graphene.  They grip fine.  My first SR red duplex KILLED my $40+ hospital grade Hubbles.  I gave my friend an SR black duplex to replace a cheap dupex-he was overwhelmed at the difference.  I have a relatively higher end system and his is very fine as well.  I began my journey into duplexes about a decade ago.   Sure, SR duplexes aren't cheap, but in three systems including mine, they are a bargain in sound quality improvement over standard duplexes.  

I have some Porter Ports here, as well as some Acme Audio Labs Ag Silver Cryo receptacles and one Furutech GTX-D G receptacle.  I suspect the differences are subtle and I don't really have a clear preference.

As to Rhodium vs. Gold vs. Silver plating, I suspect any potential differences may be due to the level of finish on the plating (polishing?) and maybe also how the current is transferred across the boundary.  Maybe the different platings impart a subtle sonic characteristic as some believe they do when used on speaker cable spades, etc.  These platings were mostly used for corrosion resistance in the early days, like the tin coating you can still find on some wires and connectors.  Other than silver, none of the other common plating materials conduct electricity anywhere near as well as copper, although gold comes closest at 76% IACS.
