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.

Well, let's see.  I am using, for now until I can find a decent used ARC amp, the Hafler 500 I built myself (they used to sell it as a kit) sitting at the desk in my shop in 1975.  Had it tested a month ago.  He adjusted the bias and it measured at spec in all areas, old caps or not, I guess.

Reason for visit to the shop:  Added a newly purchased ARC SP-6 from the late 1970's.  Replaced two parts in that and it measured excellent by the tech, who is actually an audio engineer of high repute with all the right measurement gear.

SO, how old is too old?  I have no idea, but I am very pleased with my system on my Tympani I-C's, which sound like they did 40 years ago.  I have another pair that was completely rebuilt by Magnepan, but they are still in the box until I move.

Would I LIKE new ARC and Maggie stuff?  DUH!  Unfortunately, I am retired now and just can't justify the expense, so while the stuff is definitely old, it plays music that sounds the same as when I plug in my guitar or bass, or play my cornet or drums, which is the standard I personally use. 

Would new stuff improve the overall sound? No doubt--progress has been made in every field.  If you like what you are hearing, go to a GOOD, PROFESSIONAL shop and listen to new gear in your price range.  TAKE IT HOME and plug it into your current stuff and listen.  If you like the new stuff and can afford it, buy it, I guess.

Remember, as everyone here knows, your ROOM is the most important part of any system for reproduction accuracy.  Either way, enjoy the music!

Cheers!
