is there something inherently special about R2R?Yes there is, it does 16/44 24/96 Redbook pcm bit perfect,, when implemented right, better than any dsd/sacd delta sigma can hope to, which can only give a facsimile of it.
MoJo Music:
" When a PCM file is played on a DSD or Bit Stream Delta Sigma 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 Delta Sigma DACs do a poor job of decoding PCM."
