To test the heat theory - hy don't you just heat up the CD with a blow dryer and do a listening test?Also, I don't use a large demagentizer - just a Nakamichi tape dead demagger. Seems to do the job and yet because of its small size it is quite unlikely to heat up the CD as you are covering only a 1/3" x 1/10" surface area at a time, "painting" the CD with the device.
I think the fact that the the demagnetizer thingie works on CDR's as well means that it cannot exclusively be based on physical expansion and changes in the metal due to heat, as the reflective surface of a CDR is perfectly smooth and the "pits" are just darkened areas in a gel layer above it.
Another interesting comparison to do: demag a CD that has almost no silk screening and a CD that is packed with a 4-color full CD paint job. On my tests, the thicker the paint side, the more pronounced the demag-effect was. Now, just to make sure I wasn't dreaming, I have to go and heat these CDs up and see what happens.
