Question 433

Why do some CD players sound better than others even if the CD is seriously scratched on the bottom half?
At this point, there should be very little difference between CD players that are playing perfect CD's. They all create almost distortionless reproductions of the original sound. However, different players use different tracking techniques and optical systems and thus have different abilities to recover from imperfections in the CD.
