DAE Tests

- Test Method:
We used CD DAE 99 v0.21 beta and EAC v0.9 prebeta 11 software in order to check the DAE performance of Ricoh MP5120A with various AudioCDs (both pressed and CDR). The posted DAE results are the average of both applications, but the CPU usage was only taken from CD DAE 99, since EAC occupies the system a lot more. As a last note, we used the "BURST" reading mode of EAC. We made a full CD Rip starting from the first to the last track of the CD. The Average DAE reported speed along with the CPU Usage is displayed in the test graphs.

- DAE features
As the EAC v0.9 prebeta 11 reported, the Ricoh MP5120A doesn't "Caching" data, supports "Accurate Stream" and "C2 error info".

- Pressed AudioCD results: (Click to see CDSpeed Graph)
The Ricoh MP5120A supports up to 32X DAE speed at both pressed/CDR media. Its average performance was around 22.8X:

- CDR AudioCD Results: (Click to see CD Speed graph)
The Ricoh MP5120A drive better performance with CDR media than with pressed CDs:

- EAC Secure Extract Ripping mode

After many requests from numerous visitors we have added the EAC's secure extract ripping mode results, which ensures maximum produced WAV quality. Note that for each drive we used the build-in detection function:

- Advanced DAE Quality

All drives performed excellently in the Nero CD Speed Advanced DAE quality test. The Ricoh MP5120A produced 0 data/sync errors and got a perfect score (100). As the Nero CD Speed Advanced DAE test showed, the drive can read "CD-Text" and "SubChannel Data":

- Bad CDR Media results

Despite the fact that Nero CD Speed Advanced DAE test stretches a drive's mechanism to the max, we decided to do real life tests with a scratched disc. The disc was dirty, and with some light scratches, enough to cause problems to most of the tested drives. We used CD DAE 99 software to rip the whole disc (756539616 sectors) and the results were very interesting:

As the tests proved, the Ricoh MP5120A performed better than Pioneer DVR-A03 since it produced lower reading errors. However the 4.10% is considered high compared to other CD-RW drives.
