RL - there are all kinds of things that make it harder for a CD transport to read a CD, including:
1) out of round CD
2) warped CD
3) mal-formed pits
4) static charge - creates forces on the head
5) electron energy level in the polymer - can be affected by exposing to certain light frequencies
6) coating on the CD - just like multicoated lenses - changes refraction and makes it easier for the laser to penetrate the polymer
7) edge treatments - reduces the reflected energy inside the polymer
Try any of these on a truly resolving system and you will hear an improvement.
This is one reason why I don't bother with CD's anymore. Just play tracks on my SS drive.
