Steve N who by all accounts has been successful manufacturing R2R and DS DACs and is a credentialed source
Yes Charles but as I said not discrete R2R. he has to use either DS or the Hybrid.
Or he could purchase "discrete" R2R made boards from Sokeris Audio Engineering but he’ll loose his dsd capability, which means nothing to me, as it was pcm before it became that.
Here as of 2017 (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.
