"This suggestion of yours falls short in light of the fact that tests done by Boeing/Sunstrand have demonstrated cryogenic processing extended the life of circuit boards in military applications, specifically boards used in cruise missiles. As well as other tests performed by Honeywell on experimental thin film magnetic memory wafers showed increased conductivity of metallic layers, reduced residual stress between layers, and possible (but not fully confirmed) "healing" of vacancies in the layers. Even if cryoing doesn't produce "better sound" where better sound equals a more realistic replication of music, at the very least it improves component reliability by extending the life of the circuit boards.

According to Controlled Thermal Processing, Inc even the objectivists beloved "BLIND TEST" has been done numerous times and has shown that cryogenic processing of audio equipment has improved the quality of sound in virtually all audio equipment and audio equipment components."


This is a direct cut and paste from their web-site SELLING Cryo!

Once again a leap of faith is being made between "improving life of missle pcbs" and things sounding better:

I can believe the better reliability: reducing stresses in metal layers and glass substrates could well reduce the susceptiblity to vibration in flight. For a few minutes, at least :-)

As you state, this has NOTHING to do with stuffing things in your freezer at -10C.
