You can’t beat this outlet for the price.

It is a NOS Hubbell HBL8300H hospital grade outlet. It’s the real deal.

Non plated brass contacts.

A non plated brass supporting back strap.

Slim Compact body.

There are many ways to skin a cat. I used to have a bunch of the silver plated Acme Audio outlets which are quite good in and of themselves I got on a trade with Bob Crump way back when. Better than hospital grade, for sure. But there are a bunch of characteristic of IDEAL outlets and outlet covers that should be addressed as best one can. Resistance to Vibration, connection effectiveness and resistance to RFI/EMI. Clean contacts, Graphene contact enhancer as a guard against micro arcing, carbon fiber or just paint the covers with Graphene for RF shielding, and use Marigo VTS or dampers on the outlet body and the wall plate. The Golden Sound Acoustic discs are wonderful on the wall plates. Your humble scribe actually has a relevant product - Flying Saucers for Unused Wall Outlets - that prevent RF from entering the system via unused outlets in the room AND unused outlets around the house, whether they be on the audio circuit or not.
I have now tried the Maestro (very organic with great bass), the Oyaide R-1 (good neutrality with rhodium coating), and last but easily the best to my tastes, is the all copper rhodium coated (cryoed treated) Furutech GTX D NCF outlets. Expensive but easily well worth it.....like a power cord upgrade. Highly resolving and responsive from lowering the noise floor. Requires serious break in time so be aware. Ping me if you want further experience on them. 
I also will have the Maestro and Oyaide for sale if interested.
I'm using Maestro and like them very much.....I have great respect for Furutech.....use their IEC and wall plugs.
