Ne znam, daj neki link na single-bit dac. Ja sam naleteo na ovo http://www.mojo-audio.com/blog/dsd-vs-pcm-myth-vs-truth/
When a PCM file is played on a DSD or Bit Stream converter, the DAC chip has to convert the PCM to DSD in real time. This is one of the major reasons people claim DSD sounds better than PCM, when in fact, it is just that the chip in most modern single-bit DACs do a poor job of decoding PCM.
