Are "vintage" DAC's worthwhile, or is this a tech that does not age well


Hello,
whether it’s worth looking into old dac such as
Spectral SDR 2000,
Mark Levinson No.35 (36)
or so Sonic Frontiers Sfd-2 Mk2 DAC.

Digital audio is the fasted moving, now improving category out there
Because to this day they have no usb connection or other options.
But is it necessary?
Or is it better to still focus on a truly time-tested sound?

It was noticeable improvement in SQ streaming Tidal when I switch to Dragonfly Cobalt from Dragonfly Black in my mobile setup.... so DACs sounds differently to me. 
DACs sounds differently. Depends on chips used, codec, technology and resolution supported. DACs r different animals... DSD, MQA, tubed or R2R... all of them sounds differently and vintage too.
