Because HiFi Rose is an engineering-centric company (footnote 8), niceties like translation and spelling sometimes seem to get short shrift. On the RS520, linguistic quirks were never particularly enigmatic, but perfection is a ways off. When connecting to Bluetooth, the message you get is the slightly off-kilter “Execute [Bluetooth] to search for available devices.” The screen that lets you choose among three font sizes for streaming music says, by way of instruction, “Enlarge a Playback information.” Even the company’s official English-language website (footnote 9) states, “Before the sudden change, the tool until yesterday is meaningless.” Jon Derda says HiFi Rose has been “making small changes with each iteration of [the RS520’s] firmware (footnote 10), to Americanize the product further.” Importantly, the 64-page product manual is written in rock-solid English, no complaints.
