EAC has the ability to correct minor glitches and scratches, which is a wonderful thing even if you're using a lossy codec. Because you can sometimes hear a scratch (sometimes it sounds like a click, skip, or distortion) better than you can hear the loss.
True for the skips and clicks, but EAC cannot do miracles (no other ripper can do as well) ... the point is that EAC uses a "voting system" (the Re-Read concept, based on the assumtion that an error will not be read twice in the same way - this has been proven wrong in some cases) to obtain the original data with a high probability.
Plextools is my no.2 on the list with a different approach of excessive C2 error information usage to "reconstruct" defective blocks with CU errors ... problem is that you 1. need a plextor drive (newer RW recommended) which can be twice as expensive as a liteon and 2. you have to rely on your drive's C2 error reporting accuracy which often has been proven wrong (see the later cdrinfo.com drive reviews) ...
Both pieces of software use the method of re-reading with lower read speeds to gather data ... the only difference is the approach of error "correction" and the fact that EAC has the more sophisticated interface (while plextools shows a diversity in functionality).
Also we must never forget that CIRC has
never been designed for perfect data integrity under all circumstances ... the paramount object during CIRC development was to handle error levels up to a certain limit and take care that excessive error counts (CU cannot be "mathematically" corrected) pass your ears without significant audible detection by using statistical means of data weighting, interpolation and muting.
