After reading through all these posts, I think I am going to give up. So far, no one can come up with a good reason why "cryo" treatment alone works. Thus far, the best reason thus far is "because I experienced/believed it".
Put it in another way. Quite a few people not long ago argue that earth is the center of the universe because they believed so. I think we can do better than that in 21st Century.
Regarding DBT and statiscally significance, it takes roughly 8 correct answers out of 10 trials of ABX to be somewhat significant. Usually 9 corrects out of 10 is considered valid at >95% confidence interval. That's why most audio improvement can't really be tested using ABX. It's not because there is no improvement, but because human audible memory typically is a lot worse than that. After 3-4 trials, all things tend to jumble up.
I normally do not ask for a DBT for proof because a negative result actually proofs anyting. It just says that the difference can't be detected under the circumstance. Not very usefully in my opinion.
I only brought it up because Cello offered it up as evidence. Once again it's one of those insignificant results. It's certainly not his fault. It's quite difficult to set a good DBT ABX test.
