They don’t run production the way we do in the US. We have in process checks and inspections at most every step. They tend to run a product start to finish and check the results at the very end of the process.
You’re doubling down on a dubious stereotype, and I’m being charitable with my language. Many of the electronics that people rely on daily around the world (e.g. TVs, smartphones, etc.) are manufactured in China, and are obviously highly reliable.
To avoid buying a Chinese product that has received virtually nothing short of rave reviews (e.g. a Denafrips DAC) solely because it is Chinese is analogous to someone having avoided buying Japanese products in the 1970s based on a similarly anachronistic reputation.
Of course there are exceptions, as there are a huge number of companies that operate in China. But the one that we are discussing was incorporated in 2012, is a boutique operation (originally five employees; now 40-50), and has a worldwide sales and distribution agent (Alvin Chee) based in Singapore, who is exceptionally responsive to questions and/or problems with the products.

To be clear, I don’t care if anyone buys products from them, even though I am quite happy with my Pontus. I am pressing the point simply because I think that any moderately serious research will reveal that the company is well run, and makes excellent products. The fact that they happen to be a Chinese company is, in my view, irrelevant.
