Recommendations for 20 amp electrical outlets

I met Galen Carol (Shunyata) at the 2018 AXPONA and he told me a couple interesting things about outlets.

1. He recommended Hubbel 5362 outlets. He said they will perform as well or better than any exotic outlets.
2. He didn't recommend hospital grade outlets because they are built to withstand chemical corrosion as their first priority. They have stainless contacts which do not conduct electricity as well as copper.

I'm building a new house with an audio room and I will be using Hubbel 5362's for the three dedicated 20 amp circuits. However, I will have to install them after the electrical inspection because they are not tamper proof as @pcolvin mentioned.

@8th-note Buy some 20 amp tamper proof Levitons from Home Depot.  They're under $5 each. Then save them for a rainy day once you swap them out.

Per my dealer, I avoided the Furutech fancy outlets.  I have a total of six dedicated 10a circuits with 10 gauge wires (two systems).  I have a pair of Shunyata's and four PS Audio.  I can not hear a difference.  They both grip well, although I have made wall plates with semi circular supports under the bottom outlet to support my heavy cords, and they work wonders.

I replaced my circuit box and then ran 12 gauge to the HiFi.  Interesting, every box I looked at used aluminum for the breakers and hence, aluminum to copper wire. So I don’t understand all the debate over which outlet is used. From the source, we probably all have a problem with connecting aluminum to copper.  No outlet, no matter how sophisticated in materials science, will alleviate this problem.  I just needed a very good outlet to make a very tight connection and then let the DC filter and line conditioner cleanup the mess.  So far, very good .

I’ve used the Cardas for about 5 years now and remember the sonic changes to be a positive in my system.  All I have plugged in it are a REL S812

and a Parasound A21+.  
affordable and made in USA
