AFAIK, Oppo is a Chinese firm with a design center in Silicon Valley. I am not worried about parts or build quality as Apple is manf. in China with a design center in Silicon Valley. The Chinese will build to spec. so it depends on the spec. you want.
Also, given that these things can become obsolete in 2-3 years, longevity is less important.
Audiophilic consumers are often attracted to ultra-thick aluminum face plates and will overpay for such trivia...
Finally, Oppo is a major, or the major, cell phone maker in China. It is possible that they just like building audiophile equipment and make less profit on it.
OTOH, a search for photos, or reviews of build quality might prove fruitful.
