Old digital that still kicks butt
Especially well designed ones that use the very best of the last R2R ladder dac chips made the PCM1702 and PCM1704 chips and if you can get them with PMD100 or 200 HDCD filter chips, but not mandatory, after those the next best AD1862N or TDA1541
TDA1549 old early bitstream (single bit) not good musically or dynamically, don’t care what Lampi says about it.
Just use the search for PCM1704 and then PCM1702
