don't trust your ears.It's not our ears that are the problem. It's that human mind that they're plugged into, and all of the psychology that goes along with it that cocks things up and prevents us from being the precise, objective analytical tool that our egos would like us to believe we are.
The aluminum body of a cd is manufactured and then coated. This process involves heat, shaping, etc. which stress the metal. The cryo process relaxes the grain structure.
Huh? The "aluminum body of a cd is manufactured then coated"? Where on earth are you getting this misinformation?
The body of a CD is plastic (polycarbonate), not aluminum. The body is injection molded and the pit side is then coated with aluminum via vapor deposition or megnetron sputtering. The layer is exceedingly thin, only 50-100 nanometers. It's so thin in fact that you can see through it, so it's really not all that reflective in the first place and much of the laser light simply passes right through it.
Further, vapor deposition and magnetron sputtering lays down this layer by way of individual atoms so there is no "grain structure" as there is in materials wrought of bulk molten processes.
I'm sorry, but this theory simply falls flat on its face.
