Get off your racist pulpit sunshine, of course the Chinese are extremely capable, just like anyone, just look at a few these days Holo Denafrips, etc etc
T'aint racist to critique Taobao DAC offerings - I've bought plenty and implementations in general are poor. You did specifically say 'no name' and now you've introduced names. I would agree that the named guys do a much better job than the el-cheapo Taobao DACs designed by spare-timers. Early on there was one called 'raindrop_hui' but that was the name of his reseller - he was relatively clueless as regards EE but that didn't stop him selling tons of TDA1541 DACs.
