I just spoke to Jim at Purist. The outlets he sells under the Purist trademark are a special order Leviton that are then cryo treated. Sales of these are exclusive to Japan. None have ever been sold in the USA. It is possible someone ordered from Japan or entered the country with them in their suitcase.
That being said, he uses Hubbell in his own system, the same series hospital grade I use. Mine were treated by immersion cryo at NASA and the effect was well worthwhile, at least when teamed up with Purist Power cords.
If a group of you want to go together, buy a box or case of outlets, I can get a quantity discount for us for the full Purist treatment. There will be no special packaging or wrappers, but you will have ultimate performance for a fraction of the cost. (This is exactly what I did).
To alleviate any concern, the outlets for Japan are exclusive NOT because they are some incredible performance denied to the US A, but rather the Japanese prefer specialty products that cannot be compared to USA product or imported at discount back into their market.
One more tidbit, several of the outlets being touted here among audiophiles are supplied by and / or cryo treated by Purist Audio.
The last time I visited the factory to do new product photography of Purist products, there was a master case of 144 outlets sitting on the floor. When I ask about them Jim said that he had obtained them, cryo treated them and they were on their way to xxxxxx to be packed with the xxxxxx trademark and sent to dealers.
I suggest we collect as many Audiogoners together as possible and send a batch to be treated. For myself I want Hubbell. There is no reason a number of you cannot form some sub groups and send me other brands. Leviton, Pass & Seymore, Arrow or whatever brand suits your fancy. The whole bunch can go with the Hubbells and save on shipping.
Also, any one of you that can obtain Hubbell at a deeper discount than me, can obtain them for the entire group.
Generally speaking, the fewer ( larger ) packages of product that travel the fewest times back and forth, the lower cost for each of you.
Let me know.
