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?

Firmware Updates to CD/SACD/Blu-Ray players.

I typically update my camera's firmware, but for audio use of these?

I just bought a 2009 Oppo BDP-83SE (special edition, improved audio).

It has Firmware Updates, I suspect only for minor video issues. 

If all the initial reviews said very good audio, never found an audio 'problem' mentioned, why do/risk it?

Any recommendations?

thanks, Elliott
