@invalid I think what most designers mean when they say accuracy is that the wave form doesn’t change from input to output.
That’s a valid point and therein lies the problem. You can take several examples of audio components that are capable of performing this unaltered waveform function. Yet when listened to, it’s clearly recognized that each of them have their own sonic signature or fingerprints. So which one of them is accurate in reproducing music recordings? @sns comments are on the mark in regard to the concept of audio accuracy.
