Best outlet

You may want to consider Albert Porters "Porter Ports". 20 amps, already deep immersion cryo treated and one hell of a nice guy.

The Wattgate 381 Ag was recommended to me by the Cable Co. They said it was the one that their customers eventually ended up with.

I have one and it sounds good.

I second the porter ports. I have 6 of them.

Great guy in Albert, just watch out for some them jokes :) !1

Shunyata Research SR-Z1 AC Outlet
Oversized and Cryo treated. Tight vise grip which is good for heavier gauage wire.

Oyaide's R-1
R-1 Highly (twice) polished beryllium copper

Oyaide's SWO-DX

Beware:

If you have a 15A circuit and put a 20A outlet on it, it is no longer to code. If your house burns, the insurance company does not have to cover it. I was going to buy these but decided against it. Instead I bought some Hubbell 15A hospital grade outlets and had them cryo'd myself.

Just letting you know the risk involved...
