Features

Hi-Res Walkman (Signature Series): The Sony Signature Series NW-WM1A Hi-Res Walkman is built with an aluminum frame and tailored electrical components for high quality, dynamic sound from high resolution music files. The newly developed FT CAP (high polymer capacitor) works to regulate power flow, optimizing it for instant, clean power when needed. MEL type resistors are utilized to reduce noise and minimize distortion in the audio signal path. A low-resistance Oxygen-free Copper cable offers low distortion and superior channel separation.

Sony Audio Technologies: The Sony Signature Series NW-WM1A Hi-Res Walkman incorporates several Sony audio technologies for an uncompromised listening experience.

• S-Master HX Headphone Amplifier: The NW-WM1A's S-Master HX digital headphone amp cuts distortion and noise across a wide range of frequencies for rich, full-bodied sound. It features an unbalanced 3.5mm (1/8") and the new 4.4mm JEITA stereo balanced headphone jack to connect a set of headphones (sold separately). Thanks to the 4.4mm balanced headphone jack, noise picked up from the wire to the amplifier is reduced - resulting in superior sound & clarity.
• DC Phase Linearizer: Sony's DC Phase Linearizer works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match the phase characteristics of various types of analog amplifier to deliver a purer, more analog-like sound. Choose from six phase character setting.
• DSEE-HX Upscaling Technology: DSEE HX upscaling technology uses an algorithm to analyze your music and replace any lost information, so that the quality is almost high-resolution level. Choose from four modes (Female, Male, Strings, or Percussions) to bring out the best in your music.

Supported Audio Formats: The NW-WM1A Hi-Res Walkman supports the very latest 32bit/384kHz PCM and Native DSD (up to 11.2MHz) playback to help retain all the authentic detail of the original recording. It also supports playback of a variety of other high resolution and compressed audio files.
