Cryo treatment excerpt

I found the following paragraph very intresting which sheds some light on the designers reasons for using cryo treatment in a SOTA piece of gear. What the sound is like only he and owners would know.


Cryogenic Treatment
When dissimilar metals are joined, crystal boundaries form. Soldering a resistor to a PC board results in stress and crystal formation. Even before that stage, in the course of manufacturing and assembly thousands of solder joins and copper crystal boundaries form in the conductive copper layers of each PC board.

In the DA-218 processor, cryogenic treatment significantly reduces crystals formed in the copper strata of the PC board during manufacturing and assembly-related soldering. Ralph Dodson confirms that the benefits of cryogenic treatment are measurable as well as audible.
