In the following tests, we check the drive's behavior when reading scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

Unfortunately the DVR-110D could not complete the 721 & 726 CD error correction tests. Results will be updated after a new firmware release.

- CD-Check Audio Test Disc

The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction / Error correction capabilities of a CD player. The disc offers a signal combination with disc error patterns to rate the drive's abilities to read music and reproduce it completely. Five tracks on the disc contain a sequence of progressively more difficult tests. These tracks are referred to as Check Level-1 through Check Level-5.

The tracks are reproduced through a software multimedia player (e.g. Windows Media Player). Each level is considered as passed, if the tone is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested drive.

Error Level	1	2	3	4	5
Pioneer DVR-110D	5/5	5/5	5/5	5/5	1/5

This is certainly an improvement on Pioneer's previous release, the DVR-109 and a great "score" as well. Most drives do not even reach the fifth level. The DVR-110D reached the fifth level and produced only two audible clicks.
