I used to think that digital meant perfect copies too, but after playing a few data CD-Rs made from audio CDs on a PC, I would occasionally hear a small click . "Rewinding" and playing the passage again usually reproduced the click in the same spot. Playing the same passage from the original CD didn't produce the click. Using a file comparison program on my PC, I found that the CD-R copy was NOT exactly the same as the original audio CD.
Since I used very cheap CD-R blanks that were meant for computer data (free after rebate - from an office supply store), I speculate that the shortcomings with my copies were caused by the disks themselves and a few of the burned bits not "sticking."
My suggestion is to pay as much attention to the media as to the recorder, as even perfect copies may quickly deteriorate if poor media are encountered. This may not be as much of problem with the audio blanks.
The freeware I used was called Test Path, if you wanted to check with your PC how any old copies are holding up.
