*** The sampling process adds noise and distortions. The distortions are common to the 16-bit and 24-bit versions, but the 16-bit version adds more noise. ***Incorrect. If the same ADC converter is used, both 16-bit and 24-bit versions are decimated from the same sigma-delta modulated stream. any noise and distortion (eg. quantization error) is determined by the sigma-delta modulation and not by the final output format.
the only difference is the 16-bit version discards any information below 16-bit.
if recording the analog output of a cd player, there is no real information below 16-bit - in fact it is doubtful there is any real information below 14-bit due to noise added by analog circuits.
like i said, if you disagree, please provide proof in the form of validated double blind testing results.
