Lifespan of a quality solid state amplifier?

What is the expected lifespan of a quality solid state amplifier (Krell, Mark Levinson, Anthem, Bryton, Pass Labs)? Is their any maintenance that can be performed to extend the lifespan of one of these amps?

Regards,
Fernando

Had a PS Audio 200C amp years ago and it began sounding lifeless with a cracking sound audible. Called PS Audio and the tech said that after about 20 years the caps are pretty much shot. Which led to my purchase of a Belles 350A.

...I will not be responding further since you clearly have no intention of accepting the overwhelming body of evidence that contradicts what you say...

No, caps age. The thread was how LONG and how WELL and amp can sound as it gets older. To go to some of the extremes in this thread would be to toss out an amp as soon as time changes. The discussion was NEVER that caps don't age (you seem to be hell bent on thinking I don't know that), it was how gracefully they age. Nothing contardicts what I say. A fifteen year or older amp can sound pretty darn good. Remember too, that caps are selected to provide the best service and sound where they are used. SS is a wonderful thing...for a long time.
