What is the average life expectancy of a DAC?


Hello folks, 

With the recent profusion of relatively inexpensive DACs that are now available, I'm wondering what the average life expectancy of a good DAC is? Or, to put it another way, is it cost-effective to invest in a high(ish) end DAC like a Denafrips Terminator or a Halo May with the expectation that it will last at least 5 or more years?

Thanks!

An expensive DAC is a fetish object for many here! The more costly the greater the claims for aural "thrills"! 
DACS that live  in the wild have a much shorter life than domesticated DACS. My DAC was a rescue DAC and while we’re not sure of its real age, it’s probably about six months old, 
30 years is not too short a life span for a DAC.  There are a couple of thigns to consider though:
1 - DAC's after 2010 got much better, especially with RedBook playback so buy older models with caution.

2 - Streaming services and connectivity changes more rapidly than resolution and bit rates. 

Best,

Nobody can tell a $100 DAC from a $1000 DAC if they listen blindfolded
That’s an interesting claim. Please tell us about your listening tests that have led you to this conclusion.
