With the majority of the world's music catalog available in our pockets anywhere, anytime, any old-school, standalone player is going to need a good reason to exist. The Sony Walkman NW-ZX300 Music Player has more than one. For starters, it supports high-resolution music formats like DSD and uses proprietary technology to upscale compressed audio. Its S-Master HX amplifier eliminates distortion by keeping things 100% digital until right before output, and the standard mini-plug jack is joined by a balanced output that delivers entirely separated right and left channels, as well as LDAC transmission for a wireless experience far superior to regular Bluetooth. Finally, it can also function as a DAC for your computer when connected over USB, improving the audio quality of everything from Skype calls to YouTube videos.
