What Is Bit-Perfect Playback?
Bit perfect playback refers to the ability of the soundcard to pass an untouched digital stream through its S/PDIF port to the connected DAC. Signals such as PCM, AC3, DTS, etc, require bit-perfect for proper playback.
Bit-Perfect is also required for proper playback of CD's using an external DAC.
