Lifespan of amps and preamps?

Hello.  I have been listening to the same NAD 1240, Adcom GFA 535, and B&W dm 620s since I was 20 in 1990 (it was a big deal to buy all that as a 20 year old kid...).  Other than doing a thorough cleaning on the adcom a few years back when it stopped working, I have literally done nothing to these components. 

Are they totally dated, meaning past their intended lifespan from an internal component perspective?  I have to say it all still sounds really good to me.  But I never really listen to other systems.
Thank you for any input!
Scott.

Never change a running system... But if you want to get an upgrade, you can also have a deeper look on used (but not vintage) equipment. Many of the high end gems I got over the last years were used but in great shape. Never forget that also loudspeakers are ageing over the years. And that technology advances. I recently tested the new Monitor Audio Gold 200 and it outclassed my Infinity Kappa 7 II Series 2 in almost every way you can imagine despite of being significantly smaller: more resolution, more precision and very clear bass. So visit some dealers with a good portfolio and proper showrooms, discover the 2020 high end world and enjoy!!!

Addendum: I myself am into vintage for a long time. It can get you a lot of listening pleasure, but it can also cost you a lot of money for maintenance and repair. So think twice before buying "golden oldies"...

So long, Hans
