Audiophile Grade Wall Receptacle

@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. 

The elephant in the room: Sometimes there is no clear answer to our questions and/or scientific testing that can prove an occurrence or answer a question. Trust your ears and be your own judge.

Just to end this discussion (for me anyway), I will do my ultimate comparison.  I have purchased 70 feet of Romex 10/2 Simpull wire and ordered Furutech GTX-D(R) Duplex Receptacle, FI-32M(R) Plug and 106-D-NFC Receptacle Cover.  Now I know the 10/2 adds nothing to the party as 12/2 would provide all the current my system will ever need and the 20 amp breaker can draw, but I found Lowes was selling the 10/2 at a cheaper price than Home Depot was asking for 12/2 so I bought the heavier cable.  I will be running the new line out of my mechanical room directly into my garage and up to my listening room.  Meeting all code requirements along the way.  When done I will be able to demo equipment on 15 amp vs 20 amp.  Furutech vs $2 contractor plug, with and without power conditioiner in the loop.  This will take about a week but I will make a full report for anyone interested.  Open to suggestions on musical selections that may provice the best opportunity to hear the difference.  Cheers.
