What is the difference between DVD-audio and Super Audio CD?
DVD-audio was developed based on the video format (DVD video) while the Super Audio CD was developed based on the audio format (CD). DVD-audio is based on PCM frequency and longer word lengths. The Super Audio CD, however, is based on a superior recording technology called Direct Stream Digital (DSD) that more closely reproduces the shape of the original analog waveforms to produce a more natural, higher quality sound that more accurately captures the nuance and atmosphere of the source material.
