I use, buy, and sell digital equipment based on a sliding scale where I anticipate that low-cost gear has a shorter life and expensive gear a much longer life. I don't expect the little Topping pieces to last 10 years, but the value per year is high if they get past 5, so I'm cool with that. I expect any DAC costing $1,000 or more to last until it is obsolete. I expect my expensive iMac 27" to go 5 years without a fail, and so far, both my late-2014 and mid-2011's are still going strong. Both my 2012 Mac Mini servers are likewise running without ever a down day. These are expensive machines. My kids' chromebooks and less expensive wintel machines -- crummy, things break.
Contrast this with things I bought in the 1970's and 1980's. Receivers, amps, don't even get me started on cassette decks and tuners, speakers, etc. -- those things were expected to need repairs, and they did.
Things run down, entropy runs riot. All I expect is solid value-for-the-money, and Topping, for example, has delivered on that score. I won't cry if my D50 dies in 4 years, or even 3. Now, if my Benchmark or RME things break, I will be royally pissed.
