Th electronic components will last a long time. The only real question is whether advancing performance will leave the high(ish) end DACs in the dust.
But consider that the performance of a DAC will NOT diminish. It will stay the same (as long as the electronic components do not wear out) or maybe even increase as caps are used. So a given DAC will be as good in 10 years as it is today. It is only the improving performance of the competition that will change.
