A DSD file has to be “camouflaged” so it appears to the DAC as a PCM file and thus can be used with USB audio. This is called DSD over PCM (DoP). The firmware in the PureDAC detects such files and restores the original format.

Page 10: Headphone Amplifier
Headphone Amplifier DAPC The headphone amplifier section of the PureDAC is a unique and advanced design. A precise description of its function would be “Digital / Analog-Power-Converter” (DAPC). This means there is no additional amplifier stage and the headphone amp’s voltage is generated from a special type of I/V converter, which is an integral part of the DAC. -
Page 11: Balanced Headphone Drive
Balanced Headphone Drive What is Balanced Drive? In all stereo headphones there is a driver for each ear which is directly wired to the headphone plug. A headphone is a passive device, so an amplifier must supply the electrical energy to make it work. Most amplifiers have a single active output delivering the music signal related to a static ground. -
