I have heard of the benefits of Cryogenic Processing and I can visualize how metal may have increased durability due to the process.
But:
How can it make CDs sound better?
Why would a brass instrument sound better if frozen (seasoned)? How can they be sure it won’t make the sound worse?
How can it make electronic audio components produce “Better Sound Reproduction”?
This site has some info but there are other that make similar claims.

WIth all these sites, it comes to the same thing.
Have they done scientific tests?
If a process improves sound reproduction, then people ought to be able to tell when it has been used, in a double-blind test.
Otherwise it’s a scam.
Get immediately suspicious of anything that claims to make CD’s sound better.
CD’s are digital. Ones and zeros. The information on them is “perfect” in an information science sense. It doesn’t matter whether you’ve got shiny 1’s and 0’s, colored 1’s and 0’s, or cold 1’s and 0’s. The information is in the bits, not their physical form. People who claim you can improve them by freezing, “greening,” or other manipulations don’t understand how the media works.
The only way to change a CD’s sound is to degrade the digital signal; which in the vast majority of cases will make it sound “worse” – or more likely not play at all. Think “scratches,” “fingerprints,” and “damage from freezing or covering with a green magic marker.”
This one, I can answer definitively. The material of which a wind instrument is made is irrelevant, since it’s not the walls vibrating, it’s the air inside. All the brass (or silver, or wood, or whatever) does is provide a shape for the lump of air. It’s conceivable that some new materials science would enable one to make a better instrument, if it allowed for delicate, detailed shapes which were somehow more optimal, but this would have to be an instrument custom-designed from scratch for that purpose. Dunking a normal trumpet in liquid nitrogen isn’t going to change the shape, so it won’t change the sound.
The answer is the same, though for different reasons, for a CD. CDs contain digital data: Any given pit is a 1 or a 0. It’s already possible to get data off of a CD with error rates of far less than one bit per disk, and if there are no wrong bits in the reading of a disk, then you’ve gotten all of the information that’s on the disk. Nothing you can do to the disk could possibly get you more information, or more accurate information, since there just isn’t any more there. You could, though, make the CD worse, if you damage it somehow.
