To what degree do you believe tracking error or poor
error-correction in CD players contributes to sound
quality?

Almost entirely dependent on the condition of the player. It's pretty safe
to assume that most players are in good shape right after QC in the factory.
As soon as they are shipped the downhill slide begins. That slide ends when
the player becomes unusable in the eyes of the user.

The hidden agenda in any discussion of CD player sound quality is whether or
not the player has deteriorated significantly.

How important do you rate efficient
error-correction in the design of a CD player?

Error detection and correction is standardized. All players that meet the
redbook standard are basically the same in this regard.

Error generation is not standardized.

Exactly. Which leads to another question: Is it possible for different
pressing plants to generate different rates of error in a disc, and
what effect does this have on sound quality even in a new player? IOW,
will a player sound significantly worse when operating at near "full
correction", if that term is valid. Has anyone ever done mass
inspections of discs from different plants to check error rate?
