How old is too old for a Dac?

" Also, I think today’s designs have better analogue stages than older DACs. This may be the reason for the most dramatic difference in performance between DACs. This allows a more natural presentation, even the budget models."

@lowrider57 just curious what makes you say this? I don’t think analog output stages have changed that significantly in the last say 25 years or so if not longer. A well designed output stage is something you can find on many older well designed units including the AN dac i mentioned above/

spoogemonkey, I'm not sure, since I only moved up to higher-end gear about 12 years ago. I've noticed the most noticeable improvement is in budget DACs and CDPs. New units sound smoother, more realistic than those of the 1980's and 90's.

I have an older ARC CDP ($5000), and there are better sounding units for less than $2000 now.

@jond , I really should have stressed that entry-level, or budget units have had the greatest improvement. I’ve heard Esoteric and Naim CDPs years ago and they have always had superior sonics. My friend’s digital in the 1980s rivaled his analogue setup.
IMO, there has been a "trickle-down" effect of technology that in the past was only available to high priced digital.

@lowrider57 ah well that makes much more sense and I would agree in fact generally speaking I think budget gear, not just Dacs, do sound better than they used to. Cheers.

@jond , yeah, sorry about that blanket statement. I should have reread my comments before posting them.
