Wow this thread got active... most of you must be in a different
time-zone than me ;-)

Again you misread my post. I was comparing the digital recording to an
analog soundwave or may be converted to an analog electrical signal,
but not to vinyl. When you read "analog" you replace that with vinyl. A
digital recording of a soundwave is never closer to it than the
electrical signal that comes from the microphone.

It might not degrade it but it changes it and many people hear it. Come
on, some people can even tell you the make and brand of the DAC used
just by listening to it's output. Just like some people can/could tell
you which tape-recorder or even brand of tape was used for the master.

I believe the test would prove that the two conversions changes the
sound and that this change would even be apparent when replaying it on
vinyl. If, like you suggest, no one can hear a difference, you have
proof that the two conversions do not result in a audible difference.

cheers,
Nick.
