The materials used in electronics are highly fabricated and the manufacturing processes used impart or induce stresses in them. In addition, welding and soldering adds additional stress from concentrated areas of heating. Most everyone recognizes that welded components often fail AT the weld -- a "weak" spot. The weakness comes from residual stresses inherent in all materials, further exacerbated by manufacturing techniques or processes.
Cryogenic treatment releives stresses and normalizes (or stabilizes) welded and soldered areas. This mechanism is founded in the observation first made by Bose (of Germany) and later by Einstein, that matter is at it most relaxed state when it has the least amount of kinetic energy (or molecular activity). Absolute zero (-459 Farenheit) is that point where no more energy can be extracted, or when a material is at its most "relaxed" state. While our Cryoset (R) thermal treatment does not get to absolute zero, you can understand how going to minus 300 degrees Fareneheit for an extend dwell time enables the material to become more relaxed and stress relieved.
The process makes a permanent change and the benefits do not deteriorate over time or upon return to operating temperature, it changes the whole way the vacuum tube performs. The major benefit has been a dramatic improvement in dymanic range. Bass response has been clearer with reduction in microphonics. The most starling fact has been how the tubes operates under saturated and overdriven conditions. This has made some of the more basic guitar amps sound fuller and warmer.
