However, it’s a different kind of chip than delta-sigma DACs.
Yes Delta Sigma (DS) is not R2R, it took the place of R2R chips because it was far cheaper to make and it could do sacd and dsd.
But to me it (DS) can’t do PCM Redbok 16/44, 24/96 or DXD "bit perfect" like R2R' can, it can only give a "facsimile" of it
