Features

WM1AM2 Walkman's aluminum alloy frame

Aluminum frame

An aluminum alloy frame provides a highly rigid case that's resistive to electrical noise and other interference for stable, high-quality sound.

Close-up of circuit board showing the S-Master™ HX digital amp technology

Faithful sound reproduction

S-Master™ HX digital amp technology, independently developed for Walkman®, is compatible with the Native DSD format and supports balanced and high-power output. It reduces distortion and noise across a wide range of frequencies, for rich and full-bodied sound, further enhanced by new high-quality sound lead-free solder.

An even stronger power supply

The WM1AM2 boasts an even stronger power supply than its predecessor, not only in the analog block but also in the digital block—an idea inspired by our flagship digital music player, the DMP-Z1.

Close-up of circuit board with large solid high-polymer capacitor

Large, solid high-polymer capacitor

Adopted as battery assist for the amplifier block, the newly developed large solid high-polymer capacitor offers large capacitance and low resistance. Able to instantaneously supply large amounts of power, it can accurately output signals by preventing sudden falls in voltage. This contributes to clear, powerful, and accurate bass sound as well as clear vocals.

Circuit board featuring FT CAP3 (High-polymer capacitor)

FT CAP3 (High-polymer capacitor)

Custom-made for Sony and tuned by Sony engineers, FT CAP3 is adopted for all bypass capacitors in the audio block power supply. Drawing on know-how cultivated in high-end home audio development, it has helped to improve sound expression and create a smoother sound, with a wider sound space, more transparency, and tighter bass.

OFC milled block

OFC milled block

An OFC milled block covers the digital block, helping both to strengthen digital ground and improve noise shielding from digital block elements such as the application processor and memory devices. The result is a clearer sound that appears to rise up from silence.

Circuit board featuring high-polymer capacitors

High-polymer capacitors

The high-polymer capacitors within the WM1AM2 are used to strengthen the power supply of the amp block for unbalanced output, enhancing low-range reproduction performance for a more expansive listening experience.

Circuit board featuring film capacitors

Film capacitors

High-quality film capacitors deliver voltage with a linear response across frequencies, resulting in reduced distortion and noise.

Circuit board featuring winding inductors

Winding inductors

Replacing the conventional laminated capacitor, winding inductors in the digital block power supply contribute to a pure sound. 

Low-resistance oxygen-free copper (OFC) cable

Oxygen-free copper cable

A low-resistance oxygen-free copper (OFC) cable offers low distortion and superior channel separation.

Circuit board featuring crystal oscillators

Crystal oscillators

Two compact low-phase-noise crystal oscillators ensure precision clock stability at sampling rate multiples of 44.1 kHz and 48 kHz. The crystal electrode piece is formed with gold vapor deposition for enhanced electric characteristics and improved instrumental separation. This helps remove a veil and reduce noise to realize clear open sound reproduction.

Fine Sound Register on a white background

Fine Sound Register

The surface mounted Fine Sound Register ensures even, effective distribution of power to the circuit components, for consistent sound quality.

Circuit board featuring reflow solder containing gold

Newly developed reflow solder containing gold

This is the first time Sony has used reflow solder containing gold, and it features extensively across the circuit board surface—so the overall effect is significant, including improved sound localization and a wider sound space.

A spool of high-quality-sound solder containing gold

High-quality solder containing gold

The exceptional conductivity of gold ensures absolute minimum signal loss. For clearer sound and vocals, a premium, audio-grade lead-free solder with a small amount of gold connects the circuit of the WM1AM2 to the battery.

Low dielectric circuit board and filled via

The printed circuit board uses low dielectric material to realize accurate signal transmission, while the via holes are filled with copper to further reduce impedance. The result is a wide sound space with clear, bright sound. [A] Normal via [B] Filled via

Optimized circuit board layout

By dividing the Audio block and the Power/Digital block, the circuit board layout has been optimized to ensure sound quality is unaffected by digital interference.

Graphs showing how the DSD Remastering Engine affects PCM (Pulse Code Modulation) audio

DSD Remastering Engine

PCM (Pulse Code Modulation) audio is resampled into an 11.2‑MHz DSD (Direct Stream Digital) ultra-high-frequency 1-bit audio stream. The single-bit stream delivered to the DAC has a character far closer to that of analog, giving you even more ways to enjoy your music.

Logo for DSEE Ultimate

DSEE Ultimate

Using Edge-AI (Artificial Intelligence), DSEE Ultimate™ (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. And the evolving algorithm now delivers even greater benefits for CD-quality (16 bit 44.1/48 kHz) lossless codec audio. Restoring acoustic subtleties and dynamic range, it provides a richer more complete listening experience.

Icon for Vinyl Processor

Vinyl Processor

Give the warmth and character of vinyl back to your digital tracks. Enjoy subtle reproduction of the low-frequency resonance, tone-arm resistance and surface noise to deliver an authentic listening experience.

Graph illustrating the effects of DC Phase Linearizer

DC Phase Linearizer

Our 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.

Close-up of the balanced connection and the 3.5‑mm audio jack on the WM1AM2 Walkman

Balanced connection

The Walkman® features a balanced single plug, designed for the ø4.4‑mm balanced connection cable. This separates left and right sound signals, while minimizing signal transmission loss and resulting sound deterioration. 

Logo for Hi-Res Audio

Every note as the artist intended

Take your digital music collection to another level with High-Resolution Audio. By capturing and reproducing digital audio at a higher rate than CD (24-bit/96 kHz and beyond), High-Resolution Audio allows you to get closer to the original studio recording.

Logo for DSD (Direct Stream Digital)

11.2 MHz DSD Native/PCM 384 kHz

Supreme quality with 11.2 MHz DSD native using balanced headphones and PCM 384 KHz/32-bit support.

Logo for Hi-Res Audio wireless

Hi-Res Audio Wireless

Enjoy High-Resolution Audio quality without wires thanks to LDAC, our premium wireless codec. With 3× the bitrate of standard BLUETOOTH® technology, you can enjoy a superior listening experience for all your music.

Logo for MQA

MQA™

The Walkman includes MQA technology, which enables you to play back MQA audio files.
