Interger mode explained

Damien Plisson, developer of Audirvana OSX music player software,  has published a white paper (in conjunction with AMR Audio of UK) explaining the importance of player software and Mac's playback Integer Mode.  As of writing, only Audirvana and PureMusic v.1.8 offer such capabilities with compatible DACs.

Abstract
In computer audio, the player software replaces the CD drive as the transport feeding the DAC. Ensuring bit‐perfect output of the original audio signal is a pre‐requisite, while minimizing jitter and RF interferences are still strongly needed. This paper explains the main factors impacting sound quality on the computer side, and the means that have been implemented in Audirvana player and the AMR DP‐777 DAC to boost the audio experience to the next level above the normal iTunes. These main means are bit-perfect, sample rate switching, asynchronous transfer and Integer Mode.
