Audiophile Grade Wall Receptacle

I use Cardas AC outlets.

I also endorse the top of the line Furutech receptacles. I have tried hospital grade and Synergistic Research and although they they were better than the standard home receptacles the Furutech was an immediate and obvious  improvement over anything I had tried before.

You want copper not cheap hospital grade brass.

Agreed 👍

"Hospital grade" is not the equivalent of the higher quality Furutech and Oyaide AC outlets suggested by @ebm  and others in this thread. Material choice and level of construction matter.

But the whole electrical system behind your wall and to the street and to the power company is made of non-audiophile grade equipment. Putting a special outlet at the wall just before your components doesn’t improve anything. It’ll just pass through the noisy electricity that is already there. Fortunately, the engineers that designed your equipment account for this in your devices’ power supplies… where that AC gets converted to DC to power your electronics. 

The Furutech outlets are nice and Cardas outlets are also supposed to use a copper base  For copper on a budget, might also take a look at this one and this one.
