What is the lifespan of a good SS Amp


Consider to go for a used SS Amp.
Around 4-5 years old.
Wonder how long one good SS Amp lasts.
I know that some 20 yo tube amps cost more than their
original retail price and they may last for centuries
(just need tube change)
but wonder how it is with the SS.
If I go for 4-5 yo SS Amp will I be able to enjoy it for a long years or after another few years it will start giving me problems.

Thanks for your help.

I own a Jeff Rowland 302 amp."It's a proprietry digital switching power circuitry amp and not a class D amp", in the words of one Stereo Times reviewer. Jeff calls the circuirty MECC (Mutivariable Enhanced Cascade Control). This amp hardly even gets warm. I was wondering what kind of longevity this type of amp would have?
