Good question. I don't think there is really much required in the way of care and feeding. I am on more than 20 years on my PS Audio 250 Deltas, and they still sound fantastic.
That said, there are problems that crop up with amplifiers, tubed as well as solid-state, lord knows why.
Not sure that there is really a defined lifespan, but for the prices we pay for some of this stuff, it should be forEVER, right?
