Ricoh MP7163A CD-RW

4. DAE Tests

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 the Ricoh MP7163A 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 program reported, the drive doesn't "Caching" data, supports "Accurate Stream" and "C2 Error info".

 

- Pressed AudioCD results: (click here to see the CD Speed graph)
The Ricoh drive supports up to 32x DAE with both pressed and CDR media. The drive uses full CAV as the main reading technology. The drive had the same exact performance as the AOpen CRW1632:

Since both drive share the same components, its natural their performance be the same. In the DAE test, both drives have 23.3X average DAE speed and the Ricoh seem occupying the CPU less than the AOpen one.

- CDR AudioCD Results: (click here to see the CD Speed 99 graph)
The drive performs quite well with CDR media. The average DAE was around 23.4X:

- EAC Secure Extract Ripping mode

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

- Advanced DAE Quality

The Ricoh MP7163A performed excellently at the Nero CD Speed Advanced DAE quality test. The drive produced 0 data/sync errors and got a perfect score (100). The drive cannot read "CD-Text" enabled AudioCDs and can read "SubChannel Data" (from audio tracks):

- Bad CDR Media results

Despite the fact that Nero CD Speed Advanced DAE test stretches 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 in order 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:

almost 0%
AOpen CRW1632

88,74%

As the tests showed, the Ricoh MP7163A has better DAE ripping speed/quality when scratched CDs are being used. The drive managed to rip the entire CD with a DAE speed of 20.6X and produced only 949 errors. The AOpen drive needs much improvement since almost 88.74% of the read data were not correct.

As we can see from the above graphs, the Ricoh MP7163A does not have any problem ripping both 90min and 99min CDs.
