Rpg, CDP cannot read each sector multiple times since it is operating in real time. Small errors like scratches up to 4mm along the track will be corrected while scratches longer than 8mm will be audible (pops). Between 4 and 8mm player interpolates missing data (thanks to Cross Interleaved Reed-Solomon error correction code).
When you read music CD as data, drive reads each sector multiple times until it gets right checksum. This process will eventually make CD-R or server file copy that plays better (without interpolation) than original CD.
There should be very little difference on brand new CDs without scratches or fingerprints, but it might be audible on older, less than perfect CD. Important is to use ripping program that reads CD as data. I use MAX for Mac with "Do not allow to skip" option set.
