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

@charles1dad +1.

My current DAC and the one in my friend’s system (Michael Spallone, who modifies the Synergistic Research MPCs here and the other site), both have NOS DACs with older chips and we’re thrilled.
Michael’s system is the most three dimensional and holographic system I’ve ever heard with unbelievable depth.
Oh, and he doesn’t even have a standalone DAC, he has a CD player.

@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.

@minorl You can always put a USB to SPDIF converter between your Aurender and DAC. That’s what I do after my computer. My DAC only has BNC input.
