Card-carrying vintage DAC user here, too.
Theta DS Pro Basic (AD1860)
Monarchy M22 (PCM1863)
Musical Fidelity Digilog (1541 crown)
Micromega Duo BS (1545)
Somewhat new, but with old tech:
Lite DAC-AH (8x 1543)
Border Patrol DAC SE (again with 1543)
I do have a newer Bryston BDA-1 and a Schiit DAC but seriously, they get the least amount of play. Also have some 1540 CD players (Marantz CD74, B&O CD-X). I find that with these older DACs, I get a deeper sound, more involving, maybe less obviously resolute, but nonetheless, everything’s there but with a little extra that makes you listen more.
In fact, even with say, the lowly Lite DAC streaming WBGO New Jersey into a 2A3 SET / MM de Capo-i’s combo, I’m hard pressed to say I would want more, sometimes can’t even bother to play vinyl.
