Is there such a thing as a FOREVER DAC/streamer?

I know I might be talking about rehab in a back alley, but here it goes.

I've been looking to upgrade my Hegel H390's internal DAC. But I would only do it to knock it out of the park; as the Hegel's internal DAC does an admirable job. So the question is, is there such a thing as an end game-forever DAC. At the end of the day, DAC is a digital product. Digital technology evolve quicker than analog technology. 

Will that Lumin X1, Bartok, Dave, etc be obsolete in 3 years? Thus making this a moot conversation...
