Plextor PX-40TS DAE Graph (Sync on)

Various Rippers Results:

Test Method: I used CDFS, EAC v0.85b, WinDAC32 v1.49 & AudioGrabber v1.50 to test audio capabilities.

Tested CD: The Chemical Brothers "Dig Your Own Hole" - Track :  5 (Setting Sun)

Comparing Method:
- Ripped Track 5 of the CD with Drag & Drop (using CDFS) and with all the other CD Rippers.
- 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

Notes:
CDFS Driver and Plextor Manager AudioFS capture speeds were measured using a not-so-accurate way (calculating with the time they took to complete the rip), because the program itself (or the windows explorer ;) ) don't provide any way of speed measurement. They should give you the general idea though...

Programs Settings:
CDFS Driver v4.00.130 : Drag  & Drop
Plextor Manager 2000 Audio Capture :Error Correction 100%
Plextor Manager 2000 AudioFS : Drag  & Drop
EAC v0.85b : Burst & Secure Mode / Rip Speed Default / Allow speed reduction / Error correction medium
WinDAC32  v1.49 : Burst Mode / Rip Speed Default
AudioGrabber v1.50 : Buffered Burst Mode / Rip Speed Default

Verdict of DAE Results:
As anticipated, the Plextor gave out excellent wav files, no matter what program was being used. Into this test max DAE speed was 18.88x but if you try into last tracks of CD you will get up to 24x. Plextor drives includes automatic jitter control which is responsible for high DAE speeds. All files compared perfectly, except the wav files produced by WinDAC32 (failed to give exact file size as all others wav rippers..) AudioFS gave the best possible ripping speed (up to 18.88x). AudioCapture is a little behind as it uses Error Correction method which can reduce the possibility of getting a wav with clicks, pops inside. EAC (burst mode) performed quite as good as Plextor utils.So what Plextor users must use for ripping ? 2 tools..EAC (secure mode) and AudioCapture 2000. Both are the only ripping tools which have error correction routines to reduce errors when ripping wav's..
