From what I understand, when you burn a CD-ROM, the pit shape is different from those that you buy in the store. So, to give Cdc the benefit of the doubt, maybe he is hearing a slight softening of the sound. Personally, I don't hear any big difference between my originals and the ones I burn on my computer...
Cdc,when you made this comparison, you were playing the CD and the copy on the same audio system, correct???
