Why "Cryo" anything?

Because the people who do it can then have a reason to charge you more for the product.

Well said, Lugnut.

right on Lugnut!!!!!!

Lugnut, I've not paid any attention to the arguments about cyro'ing. But your post caused me to be more curious since I generally respect your points of view. As I'm from the uneducated class I don't have to worry about my education trapping me. :-)

What I infer from your post is that because NASCAR, NASA, and INDY, have found a use for cyro'd products, that it must follow that there must also be credible uses for cyro'd products in audio related products which will produce an audible result.

While I find that possible, as are many things which lay folks don't understand, at the same time I find it interesting that there are advocates for cyro'ing just about everything in the audio chain. Is this broad based application of cyro'ing, or even a narrow based application, supported by any credible theory in physic's, or are we just talking about subjective observation, i.e. "I don't know how it works , but I hear the difference" type testimonials?

Cryo is just a form of heat treatment. Heat treatment has been used for a thousand years to modify the properties of metals, as in swords. Therefore, it is entirely to be expected that Cryo will affect the tonal quality of brass instruments.

But, just because brass instruments play music, it does not follow logically that everything related to music will be affected by Cryo. But audiophiles are not known for logic.
