DSD over USB

Normally you need a SACD player for DSD.

Your PC won't play it without converting it to PCM first.

A couple of guys formulated an open standard (DoP) allowing direct DSD playback on a PC to a USB DAC.

Not only must your hardware (DAC) support it but your media player as well.

When I worte this in 2012 DACs supporting DSD where few in number.
Today many new models feature DSD.
