Certainly, not all CD-ROM can rip 100% correct data stream from audio
CDs. But with a Plextor CD-ROM, I can reliably rip data off my disc 
with the same size and content from time to time. But writing it back 
to the CDR still sound bad. That's a problem with the recording chain
than the reading chain.

I have tried another UDMA ASUS 40x in ripping the stream off the disc,
but it doesn't seem to be as reliable as Plextor in high speed audio
ripping. The data change from time to time and not the same as the
ripped stream from Plextor.

Don't know if it is what Plextor claimed 'Capable of Digital Audio 
Extraction at 24X max with "bit-by-bit" accuracy '.

BTW, I use AudioGrabber.
