Various Rippers Results
Test Method : We used the CDFS.VXD driver and EAC v0.9 pre beta 3 to test the audio capabilities. EAC reported that the drive was capable of producing accurate stream and it also reported "caching off". Tests were made for comparing "Burst" vs "Secure Stream with caching" mode.
Tested CD: The Chemical Brothers "Dig Your Own Hole" - Track : 1, 5, 11
Comparing Method:
- Ripped Tracks 1, 5, 10 of the CD with Drag & Drop (using CDFS) and
with EAC (Secure & Burst mode).
- Edited all wavs with Hedit v2.0.04 and located the 2 following bytes (chosen
randomly)
- Removed all previous bytes and saved.
- Then in a Dos window compared them using: FC /b x.wav y.wav

Verdict of DAE Results
Sanyo CRD-BP2 has problems with DAE performance. It seems that when it rips at speeds higher than 12x, it returns errors. At speeds lower than 12x , the drive gives accurate WAV files. However, this can be easily fixed with the release of a future firmware update. Please remember that this is a pre-release drive. Other manufactures which will soon release other BURN-Proof based drives will most probably correct those errors or even make their drives perform better! However, personally, we never use a CDR-W for ripping, so we don't think poor DAE performance is a problem!
