Using the ABEX test discs series from ALMEDIO with the Pioneer K14L, we
get the following results...

75.5 points (of 100.0 maximum) |
The drive managed to achieve a total test result of 75.5 out of 100, which
illustrates the ability of the drive with the specific test disc. The total
error count is relatively low, while no samples were skipped. The performance
is rather good.

The behavior of drive was much better in this case where it managed to correct
almost all errors. The result was 94.1 points, while no muted
or skipped samples were reported.
- CD-Check Audio Test Disc
In order to evaluate the sound reproduction and error correction capabilities of a CD player (currently the Pioneer K14L),
we used the CD-Check Audio Test Disc. The disc, designed and manufactured with
error patterns,contains five tracks, with each track progressively harder
to read and reproduced by the CD player. These tracks are referred as Check
Level -1 through Check
Level -5.
Using a software multimedia player, such as Windows Media Player in this case, the five tracks are reproduced, with a clear and successful reading on each track, as long as the tone reproduced is smooth, uninterrupted, without any skips or loops. Each of the levels passed, is a percent of the reliability of the sound reproduction of the tested device.

The drive passed only the first three Check Levels of the test, but in
the third track not all the attempts were successful. The performance reveals
less than average
error correction. The fourth and the
fifth levels include an error size of 1.125mm and 1.500mm respectively, and
the drive produced continuous audible clicks over those tracks as do many of
the drives we have reviewed in the past.
