Otherwise, audio companies are more than happy to let consumers think they are the designers. For example, Emotiva amps were designed by Tonewinner. And later their Airmotiv Pro speakers turned out to be a slight redesign of a speaker already produced by a Chinese factory. I'm not saying this in any way diminishes the quality of the product, but rather to make the point that audio vendors love to allow consumers to think themselves the designers of Chinese manufactured products when they may not be.
This is true even for a lot of "high end" brands. If you look at the service manuals for Primare gear, for example, they're designed by Hansong (Nanjing) Technology Ltd.
