Fiio has rebooted the classic portable CD player with a bunch of new features that bring it into the modern era. The DM13 has a rechargeable battery with eight hours of playback. There are a remarkable number of outputs: USB, an optical port, and a line-level analog output. Plus, there are two headphone outputs (3.5mm and 4.4mm). On top of all that, it has Bluetooth support.  #walkman #cdplayer
