Why "Cryo" anything?

There are situations where science cannot explain why something works. But there are two other situations.

1.. Science explains how something works.
2...Science explains why something cannot work.

Although we are surrounded by examples of situation 2 (Dumbo notwithstanding, elephants can't fly) audiophiles have a hard time ever accepting this.

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.

The reason that liquid Nitrogen is so cheap is that it is an undesired byproduct of making liquid Oxygen, which is in demand. You get liquid Nitrogen by making liquid air (mostly Oxygen and Nitrogen), and then letting the Nitrogen boil off, some of which is collected and sold at little more than distribution cost. You are left with Oxygen, which is what you were after. How long will it be until some enterprising Cryo outfit starts using liquid air, at a lower temperature than liquid Nitrogen, and tells audiophiles that their N2 Cryo'd cables are warmed-over junk.

And regarding NASA...not everything they do is desirable. I prefer my steak on a plate, not from a toothpaste tube.

Lugnut...What's wrong with a "troll"? That's how a lot of discussion gets started. Look at how many postings this thread generated.
