Why "Cryo" anything?


Ok. So far, I have yet to think of a good explanation for "Cryo" treatment to enhance anything. Can someone explain this to me?

For background, I have a Master degree in Material Science Engineering. Here is my explaination why just "cryo" won't work.

At room temperature, the metal is already solid or frozen. Freezing it further won't do much. Most metals requires high temperature to cause any change in the microstructure or grain size/orientation/distribution. Simply freezing it for a few minutes will not change how it operates after the metal returns to room temperature.

HDM,
Lost_in_space's question 1, 2 and 3 are very general engineering questions. They can be answered by engineers with some background in thermal dynamic and material science.

I don't and can't comment on sound effect of "Cryo" treatment. So I did not. You however have experienced on such matter and tried it in a long term setting. How do you attribute the difference to "cryo" treatment? In my own subjective test, I often have difficulty pinpointing one single item as the source of difference. There are just so many variables to content here.

For example, I have often asked my wife to be the test subject and found that I can easily make something sound better simply by turning the vol about 1-2dB louder. It's rather amazing.

Another question for you on the cryo power outlet, which is more likely?

1) The "cryo" treated power outlet's contacts are cleaned and has better contact with AC plug and therefore better sound.
2) A "cryo" power outlet has a special property that results in better sound.

Why do lots of people around here always pick 2)? Is it because of the pretty pseudo science ad?

Ejliu, give it up. Those who think that "cyro" sounds better, are the same that believe that the direction of the fuse in the mains also makes an audible difference. Something about AC current flowing in only one direction, no doubt!
Salut, Bob P.
Bob P. - what does one thing have to do with the other? That's like saying people who think tube amps sound better than solid state amps believe that turntables sound better than CD players. A straw dog argument if ever there was one. You'll have to come up with something better than that!
This thread is hilarious. The naysayers don't trust their ears! And, it seems that they won't even try to listen. Success of every audio product I know of is dependent upon anecdotal evidence. No matter what the gizzmos that measure things say, if it doesn't sound good people won't buy it. In this case, especially considering that free offers were made, all one would need do is listen and then decide for themselves. The kind of fear to not try something is evidence of a problem other than audio. Whoever made mention of selecting a television based on picture quality hit the nail right on the head. Eyes are wonderful measuring devices and so are our ears. End the end the question becomes are we listening or bench testing.
