Do you want to just do PCM (Redbook cd DXD ect) or do you want to do DSD as well?
PCM is best done with R2R Multibit (Holo, Deafrips, Yaggy, MSB some AudioGD ect ect)
But if you need to do DSD as well only some of the more expensive R2R dacs can convert it, otherwise you have to go for a DSD dac which are Delta Sigma based, and the the PCM can take a hit.

Here as of 2017 (there are more now) are the companies now doing expensive to produce "discrete" R2R ladder dacs for PCM (Redbook) replay. Schiit uses a R2R chip (not for audio) but for missile guidance as there are none now available for audio use, because DS was so much cheaper to make.
Up to $3k: Border Patrol, Monarchy, Denafrips, Audio-gd, MHDT, Holo, Soeskris, Metrum, Schiit
$5-$15K: Audio Note, MSB, Metrum, Computer Audio Design, Aqua, LessLoss, Totaldac, Lampizator
$15K+: CH Precision, Aries Cerat, Light Harmonic, Audio Note, MSB, Totaldac, Lampizator
**Special mention to MSB, Monarchy and Audio Note, who never gave up R2R. Even after the takeover of delta-sigma.
