Recommendations for 20 amp electrical outlets

I just replaced my hospital grade outlets with “Furutech GTX-D NCF(R) Ultimate Nano-Crystal Rhodium-Plated AC Duplex Receptacle”. They were a notable improvement. 

I have NRG Edison and Hubbel, all on three dedicated 20amp circuits. I can't tell a difference personally when I switched components between the two.

I just had my house rewired and installed 2 20-amp outlets for my stereo wall. I used Monosaudio Audiophile Duplex Receptacle 20 Amp 125V Pure Copper Audio Wall Outlets bought on Amazon. These were wired with all 3 wires for each duplex outlet pulled back to the panel (no common ground). They’re reasonably priced and I got an almost noise free connection and my sound definitely improved ( and everything I have is connected to a Furman conditioner).

To warn everyone in the US, under the NEC code all new electrical outlets must be tamper resistant. You will be hit with this if you need an inspection for the work. Unfortunately I haven’t found an audiophile 20-amp outlets that’s tamper resistant if they’re round, only white square (decora). 

I’ve use the audioquest and it’s seems very well made, also comes with silver spades for your ground. I also use the Shunyata and can highly recommended that as well. One feature the shunyata has is the ability to grip the plug without it sagging and pulling out of the wall contacts. Great for heavy power cables. 

I use a Oyaide R1 Beryllium outlet. It has great grip for heavy power cables.
