Quality, like the physics that is the foundation for the transfer functions that drive audio equipment functionality, features, and quality and performance, is not "geographically constrained." This is because Physics works the same way everywhere...in the Universe.
If folks are using a Dell or Apple computer...those are made in China. HP laptops are made in Vietnam and Thailand.
After WWII, Japan had the same stigma attached to it: that it's products were cheap and of low quality. Then, W. Edwards Deming went to Japan.
Look at how the Japanese camera companies, Nikon, Canon, Fujifilm completely took over and now dominate the photography manufacturing sector.
Folks used to hold the same set of views back in the 70's and early 80's about Japanese cars. But the Japanese auto manufacturers consistently raised their quality game and in the 80s, Japanese auto manufacturers were building automobiles that were not only better values for the price but had considerably higher quality, as well as reliability and durability than than the US auto manufacturers. Meantime, the Detroit manufacturers were literally parking and storing incompletely assembled cars in storage lots because they couldn't deliver on a "first-time right" level of quality. Then, the Japanese manufacturers moved their operations to the USA, and maintained that same level of quality, proving once again, that quality is a product of how things are made, not where.
Coming back to audio Lumin is an excellent example of Chinese-based audio company. Lumin is a Hong Kong-based company that was spun off from the broadcasting technology giant, Pixel Genius. Lumin has excellent engineers who understand how to design and manufacture superbly well-engineered products that not only have innovative features and functionality, but are exceptionally engaging and "authentic" with respect to their reproduction and presentation of...MUSIC. These guys just...get it. Another company in this vein is Westminster Labs.
Quality is the result of HOW things are made, not WHERE.
