Sogood51 was correct in mentioning that the quality can be affected by the burning process. Jitter on playback can be reduced by altering the method by which CDR's are recorded, and this process can potentially offer an increase of dynamic range of a 16 bit recording by more than 20db.
I have quoted from a recent article discussing Yamaha's Audio Master Quality Recording below;
"Yamaha decided to deal with this by creating a process they called Audio Master. They decided to artificially slow down the speed of burning by increasing the length of the pits and lands. Although the disc is still spinning at its 24x or 32x speed, the density of bits on the CD's goes down. The normal 1.2 m/s linear speed turns into 1.4 m/s. 74 minute discs suddenly only hold 63 minutes, and 80 minute discs now only hold 68 minutes due to the extended pit length. Although the feature sizes are increased, they're still within Red Book standards. Now the reader's laser has more room with which to sample and determine if it's actually looking at a pit or a land."
