Depends on what your listening to.
If your listening is PCM, be it Redbook CD 16/44 or 24/96, DXD, or even DVD-A then go for the Schiit Yggdrasil which is R2R Multibit conversion, the best way to convert PCM.
If you want to download DSD then you have no choice you have to go the Exogal that has delta sigma Bitstream conversion, but the PCM stuff will take a hit.
Quote MoJo Music.
" 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."
