Audiophile Grade Wall Receptacle

"Hubbell catalog #5352A 20A 125V receptacle. Pure copper."

Not true, brass contacts a metal to avoid.

I know, I know, should’a put the doo-dads first.  I will catch on eventually.

Starting at the front end. And a balanced system is the way if anything is ahead of the rest best if it is at the front. Speakers cannot reproduce signals they don't receive. 

@rsf507 Glad you had the opportunity to get your hands on various premium outlets and develop your own viewpoint .  That's a pretty strong commitment in time and energy (literally).  I'll simply say that the AQ Edison got me from zero to 60 in about half a second and validated the product category as "legitimate"  in my audio world.  Your comments opened the prospects of other options in the future.

@boxcarman Evaluating components in your home in your system is the final frontier to determine where/how your disposable income is spent.  While the cost of time and energy to install premium wall outlets is high greater than many potential upgrades, many on this forum are solidily convinced that they are a worthwhile consideration. I can't say with 100% certainty that a property installed premium wall outlet will make an audible difference in your system.  I'll just say I'll take a "conservative approach" and say that I'm only 98% certain you'll like the result.
