Hi all. Over at Audio Science Review I have been messing around with some fun stuff. One was to get a really cheap audio player with FLAC playback capability. The Ruizu X02 appeared to tick all those boxes for around 20~25 USD. It was immediately purchased. Here is the unboxing and initial impressions, including a surprise twist in the FLAC support tale. Here is the partial disassembly to dig into what makes this tick and why it has certain limitations. tl;dr: This is a very, very well-built device for 20 USD. It has wide file format support but some hard limits on fidelity, with 16 bit at 48kHz being about as high as you can go with FLAC. I scratched the case badly taking it apart...but I am keeping this player.
