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

In my opinion the analogy of comparing a 15 year old PC to an older DAC is not a good example. If the priority is good sound quality then numerous vintage DACs are still desirable. This has been confirmed by many responses in this thread.

If the priority is functionality and connectivity then they do have some limations relative to current production DACs. For me,  Redbook sound quality is the more important criteria. Depends on what you're seeking.

Old DACs... new DACs... sound the same?

All this is very disturbing.

@antigrunge2  yes but if you have some sort of USB to SPDIF converter between the computer and DAC then it would take care of the jitter. Once that's done, it could go to any DAC chip. Unless I read your post incorrectly.
