Yamaha CRW70 vs Philips JackRabbit - Page 4

DAE/MP3 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 both drives 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

We used EAC v0.9 prebeta 11 to examine the drive's features. As the program reported, the Philips PCRW1208JR does not support "Caching" and supports "Accurate stream" and "C2 error info".

On the other hand, the Yamaha CRW70 supports 'Caching', 'Accurate Stream' but doens't offer 'C2 error info'.

- Pressed AudioCD results

Yamaha CRW-70 extracted the pressed audio CD at 17.2X, 3.2X faster than Philips PCRW1208JR. The CPU usage for Yamaha is 13 %:

- CDR AudioCD results

The Yamaha CRW70 is still faster than the Philips PCRW1208Jr drive, even with CDR media:

- 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

Yamaha seems to extract audio files faster than Philips. But what about quality? The advanced DAE quality test gave a perfect 100 score in both drives and a slightly better performance in the extracting speed to Philips JackRabbit.

Lets see also the rest Nero CD Speed Advanced DAE test results for:

- Philips PCRW1208Jr

- Yamaha CRW70

- 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:

Philips PCRW1208JR read our bad quality Audio test disc, faster than Yamaha CRW-70 but produced 0.24% more reading errors.

- Ripping 90 and 99mins AudioCDs

Philips PCRW1208 cannot recognize any 90/99 min media. The drive will just freeze and will not work again until you press the reset button. Yamaha cannot read 90/99 min media either, and the tests with CDSpeed gave a failure reading error in the beginning of the reading process.

- Mp3 Playback feature

Both drives support MP3 playback from CD-R/RW media. We created all possible combination of Mp3 files ,using Nero's build-in Mp3 encoder for both CBR/VBR encoding formats. The playback results are gathered in the following tables:

As the test results showed, the Philips PCRW1208JR managed to playback ALL CBR/VBR encoded mp3 files without any noticable problems. The Yamaha CRW-70 playbacks only the CBR MP3 files, encoded up to 192 kb/sec. Both drives will playback MP3/AudioCDs without any problems even under the most 'shocking' situations...We made several attempts to make the drives stop, during playback but our tries ended without any success.
