High End Components - How long do they last?


Happy New Year to everybody! Being on the high end market almost a year, I was wondering how long top level, well build high end components do last. A friend of mine has some Levinson components from the seventies... still terrific sound! Of course the answer will depent on the brand, but anyhow it would be interesting to hear different stories.

Bryston has had 20 year warranties on their audio gear for a long time now, but from what I read, warranty work is seldom needed on their products. I think that says a a lot about Bryston, but also a lot about their competitors who presumably produce equipment just as good as Bryston-- OK, some worse, and maybe some even better.

I don't own any Bryston gear, but I certainly do respect their products and their warranty policy. Cheers. Craig.
Grandpad, great to hear I'm not the only one! Wished I had'nt sold my Revox years back, nor my AR D-79. The Stasis II cost me exactly $2800 hard earned bucks! The ML X-over was used and cost $800 and I still use it today to drive my Maggie basspanels, which I forgot to mention and which are also late seventies!They still function perfectly (and so do we audio -methusalems! (: )
I still have McIntosh MC-60 mono amps from the 1950's. Is this considered hi-end? They still sound wonderful btw and I can't part myself from them.
depends: components can last a long assed time.

dynamic speakers, less so.

planar speakers, maybe less, maybe more than dynamics (depends on factors like owner is a smoker, humidity, etc).

powered speakers (like subs), probably the shortest life span.
