November 1, 1999
The key to any good CD player is its error-correction system, i.e., its ability to play scratchy CDs. In this respect, not all CD players are made alike, and it is important to know a player's capabilities before you buy it. CD-Check from Digital Recordings, is an error-correction test CD that rates a player's abilities from 1 to 5, with 5 being the best.
The 20-second test actually simulates varying degrees of scratches on the underside of the CD, with black radial lines of precise width. According to CD-Check's web site, a player with a ranking of 3 (good) would correct errors of 0.750 mm, sufficient for manufacturing defects, finger prints, dust and mechanical deterioration. CD-Check, selling for $39.95 USD, is a valuable tool for audiophiles.
