Import Settings, Use error correction

Here is the classic advice from Apple Help on what to do if you have problems importing: *If the “Use error correction when reading Audio CDs” checkbox is not selected, select it. If it's already selected, deselect it.* So apparently they do not agree with the article you cite.

People who are really concerned about top quality error correction when ripping do not use iTunes at all; they use a stronger tool such as Exact Audio Copy. But for most of us iTunes is fine.

It also helps to wipe the CD with a dry, non-static cloth before ripping.

Hi
An up for this topic.
Always the same question : use correction or not.
Nobody knows today how this function works (except Apple may be...)
When error correct is off : in case of problem, Is the player works like a cd player, creating a /making a new information or does he pass many times until having the good information.
When error correction is on : In case of problem what happend ? does he pass many times (thats why its slower...) until having the good information ?
The way is having bit perfect at the end even it is long...
An idea ?

Nobody knows ?

My mind is (In case of scratches) EC off : itunes is like a cd player. EC on : Itunes passes many times without creating information and even its longer EC on is the best way to get bit perfect . Am I right ?
