Leec, I believe you about your tests although I will try them myself, but from my understanding of how the Nespa works or is said to work, I would expect no improvement on a cd-r.
As I understand it the Nespa heats the cd and gets a closer bond between the silver cover and the substrata by removing space between the two occupied by gas. Since the cd-r has no overlay, at least as I understand how they work, I don't see how there could be any benefit. I would have expected a fourth disc where the original was Nespaed and then copied would have been best and that Nespaing the cd-r had no effect.
Since my vinyl is so good and digital is getting equally tedious, maybe I should only listen to vinyl.
