Some components too old now?


I have a traditional HiFi. Some bits are really old, but still working fine and I wouldn’t have a clue about updating even if I wanted to. Just wondering how long I can expect them to last, and whether I should pro-actively seek to update before there’s a catastrophic failure.
In particular, my CD player, pre-amp and DAC date back to around 1990, so these are about 30 years old now:
Marantz CD80 / Aragon 24k (with phono stage that I use) / Aragon D2A
Thoughts?
128x128vinyloid
Technology has improved by leaps and bounds in those 30 years.
If you can use the Marantz as a transport, I would invest in a good DAC like an Ayre Codex or Schiit Gungnir or Yggy. Not too much money, but lots of quality performance. And, they offer updates when available.
Also, I wouldn't spend more than $2K for a DAC, as they have been improving so quickly, and that $2K can get you something that will sound as good as something more expensive.

The advancements in technology have been on the digital side.  If you are happy with your analog rig I would leave it alone.  Your CDP can still be a fine transport.
Amplication has changed but not necessarily for the better.  I would get a new DAC and stop there for now.
Too old? (from 1990???) old, them components are just babes...!!!Look at folks still using equipment built in the 1950's 1960's...

And for the most part I agree with @Elizabeth, but I know for sure that DACs got soooo much better over the past few years it is completely worth auditioning them.

I agree that the analog equipment may be fine but you might want to consider a new DAC. 

Although I hope to move up a few steps in the next year I've been very happy with the Project Pre Box S2 DAC at $400. 

If not sure about the CD player might consider the Cambridge Audio CXC, $450.
