How old is too old for a Dac?


Been out of the loop for a good bit, and wondering how much things have changed in digital. In other words, how old is too old for a dac?

500.00 dollars? Extraordinary value. This small Japanese company flies under the radar outside of Asia.

spoogemonkey it all depends on the design and your price range.  I build gear and I an tell you that you have to try different units to see what works for you.  For example standard Redbook playback with a transport versus USB or HDMI connections via your PC, or looking for DSD, then that is a different story.
OP- that is a great question.
Digital, and in particular the DAC end of things, change so fast.  I've just invested a bundle in 2 DACs and they both are supposed to be upgradable via firmware updates.  Hopefully that keeps me sane for a while
