Product Research


Hi-Res Walkman (Signature Series): The Sony Signature Series NW-WM1Z Hi-Res Walkman is part of Sony's Signature series of high-quality, high-resolution audio components. Sony engineers have used only the finest-quality parts to make sure every subtle variation of sound is faithfully captured and reproduced.

  • Copper Chassis: The NW-WM1Z is fully encased in a high-grade gold-plated oxygen-free copper chassis. Widely used in instrument manufacturing, the copper lends the player its unique natural, acoustic sound. Its conductivity and raw strength reinforce the Walkman with unrivalled audio performance.
  • Advanced Cable Design: Made using advanced braiding techniques, the four wire braided cables engineered with Kimber Kable are handcrafted to seamlessly handle high power and deliver ultimate sound performance.
  • Streamlined Power: The newly developed FT CAP (high polymer capacitor) works to regulate power flow, optimizing it for instant, clean power when needed.
  • Reliable Circuitry: The surface mounted Fine Sound Register ensures even, effective distribution of power to the circuit components, for consistent sound quality.
  • Precision Clock: Timing jitter degrades the digital audio signal, creating an unevenness and distortion in the sound. A large, low-phase noise oscillator precision clock provides a timing signal to the digital audio path so each process can be triggered at the right moment.

Sony Audio Technologies: The Sony Signature Series NW-WM1Z Hi-Res Walkman incorporates several Sony audio technologies for an uncompromised listening experience.

  • S-Master HX Headphone Amplifier: The NW-WM1Z'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. Sony's Signature Series MDR-Z1R headphones include a balanced cable with the new 4.4mm headphone plug.
  • 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 settings.
  • 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-WM1Z 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.
