Generally in the world of electronics the more complex and miniaturized a device is, the shorter its average life expectancy, or in any case the useful time before a problem.
A DAC is something that works in every electronic device we have in the house, including tiny bluetooth headsets, there is no reason why such a simple dedicated device, with a large case, should mysteriously stop working after a few months. or a year, or two, if not for design errors, excessive price cuts on components, or the willingness of the manufacturer to create a tool with an expiration date.
I have an enormous difficulty in getting into the minds of those who justify the thing with the low price, thus sponsoring the most sinister form of consumerism, which by now should be contained as much as possible.
I own countless amplifiers / dacs from low cost Chinese companies, some I like very much, some less so, I will definitely buy more from some brands and stop buying from other brands as well.
What I will never justify is the throwaway policy, not even on low-budget products. We are not chickens to be plucked and I will not be treated like this, I prefer to give my money to a company that respects me more as a customer, even if I have to have a slightly less performing product for this.
