Impedance matching of ALL data lines in a CD player will make a monumental improvement in sonics. This will take some digging to make exact matches for the lines as they vary with line length. However, 25- 50 ohms works well for lines over 4-5 inches, and 10-15 ohms for shorter lines. This is accomplished by cutting the data trace at the output of the concerned IC and installing a chip R to bridge the gap from the IC pin to the trace. Also, try grounding all IC Gd. pins directly from the IC pin to the top GP.Happy listening !
