We really like the Sony NWZ-ZX1. It is a brilliant first attempt at a premium high-res audio player. Purely in terms of audio performance, it is the best portable music player weve reviewed. Its not just about sound, though: its price tag is a little hard to justify fully when you consider its lack of expandable memory and DSD compatibility, and its mediocre screen. We look forward to seeing Sony address these issues, but in the meantime, Sony can be proud of itself.Here is a list of compatible audio files this can play.. 24/192 FLAC, AIFF, WAV, ALAC, MP3, AAC, WMA playback.
