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
Programs Settings:

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!
