This may sound controversial but the answer to your question may depend on how you’re planning to use the DAC. Supposedly, if it’s intended to “enhance“ your Redbook CD playback, the Multibit options, even the cheaper Schiit Modi Multibit @ $250 could be a good option. If you’re planning to use it for streaming purposes, a non-Multibit/R2R DAC may be a better option. Same for SACD playback. That said, I doubt if the audible differences between the two DAC chip technologies in this price range will be significant.
