I believe it's Albert Porter that has his outlets cryoed at NASA. You might want to check out Mr. Porter's reputation here before heading into chuckle mode-I am quite sure that he would not be stretching the truth. While I am not personally totally convinced that his NASA cryo is any better than cryo performed at other facilities, there are many people on Audiogon who have tried the outlet he treats (I use the same outlet personally cryoed at another facility) and can vouch for its efficacy.
Before you start shooting your mouth off, here's a suggestion. Take any piece of copper wire, and measure it's resistance with a simple, cheap ohmeter. Then have that piece of wire cryoed and measure it again. It's a cheap experiment (then again, you could have an interconnect or set of speaker cables or power cord cryoed for the same cost, so maybe you should just do that).
If you want to say it's a load of crap, fine, go ahead, but don't expect me to take your opinion seriously when there's a myriad of people with real experience with cryo who have heard the differences. Some people (they tend to be in the minority) don't like what it does, but at least they've tried it.
