Co-ax v's Optical.
You are probably tied of the old co-ax v's optical digital debate,
but hopefully this will help settle the question. During another
experiment I was conducting (details to be released soon) I thought
it would be interesting to record from my Marantz CD-63se both
optical and co-ax digital streams. This went into a digital Multiwave
soundcard (with both optical and co-ax inputs) and recorded with Sound
Forge at 44khz /16 bit. The resulting files were saved as wav files
without summary data.
The result.
Both files are identical ! ... bit for bit identical. All the
stats run with Sound Forge are the same, each had the same amount
of samples, same freq response, using the "fc /b" DOS command
not one difference was detected.
The ONLY conclusion I can reach is that with my CD player and this
recording equipment, optical and co-ax digital are exactly the same.
For reference the equip used was:
Marantz CD63se
Pentium PC
AdB Multiwave Pro24 Digital Soundcard
I don't know any other way to compare the two files, so I'm happy
to say that Optical and Co-ax in equipment that is "higher end"
$500+USD is identical. I can't say this is the same for *all*
CD players and yes the result can be duplicated.
I'll be happy to provide the resulting files if someone has the
web-space available.
Regards GC
