Sony Walkman NW-ZX707 Upgraded Components

Upgraded components for an enhanced sound

We've upgraded many of the internal components so that the NW-ZX700 Series now has components you’d expect from the highest-grade player, to give it a dramatic evolution in sound quality.

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.

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, they help to improve sound expression and create a smoother sound, with a wider sound space, more transparency, and tighter bass.

Large coil for balanced output

To supply the optimum balanced output signal from the digital amp, a larger, 8mm coil is used as the L-C filter. By incorporating flat conductive wire, we've achieved lower distortion and lower resistance, which creates an improved sound resolution across all frequencies.

OFC (Oxygen-Free Copper) milled block

An OFC (Oxygen-Free Copper) 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.

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.

Film Capacitators

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

High polymer capacitors

The high polymer capacitors within the NW-ZX700 Series used to strengthen the power supply of the am unbalanced output, enhancing low-range performance for a more expansive listening experience.

Milled aluminium frame

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

OFC Cable

The low-resistance Oxygen-Free Copper (OFC) cable is used for internal headphone connection, offering low distortion and superior channel separation.

Crystal oscillators

Two compact low-phase-noise crystal oscillators ensure precision clock stability at sampling rate multiples of 44.1kHz and 48kHz. The crystal electrode piece is formed with 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.

Find Sound Register

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

High quality solder containing gold

The exceptional conductivity of gold ensures absolute minimal 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 NW-ZX700 Series to the battery

Reflow solder containing gold

Just like previous acclaimed premium Walkman models, the NW-ZX700 Series uses 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.

Low dielectric circuit board and filled via

The printed circuit board uses low and 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.

Optimized Circuit board Layout

By dividing the Audio block (highlighted in red) and the Power/Digital block (in blue), the circuit board layout has been optimised to ensure sound quality is unaffected by digital interference.

Balanced Connection

The NW-ZX700 Series series features a balanced single plug, designed for the 04.4mm balanced connection cable. This separates left and right sound signals, while minimizing signal transmission loss and resulting sound deterioration.

Unique sound processing technology

DSD Remastering Engine

PCM (Pulse Code Modulation) audio is resampled into an 11.2MHz 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 analogue, giving you even more ways to enjoy your music.

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 44.1/48kHz) lossless codec audio. Restoring acoustic subtleties and dynamic range, it provides a richer, more complete listening experience.

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.

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.

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 96kHz and beyond), High-Resolution Audio allows you to get closer to the original studio recording.

11.2MHz DSD Native / PCM 384kHz

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

Hi-Res Audio wireless

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

So immersive. So real.

Immerse yourself in sound all around you. As real as if you were there at a live concert or with the artist recording in a studio. With 360 Reality Audio, music has never been so immersive and so real. The NW-ZX700 Series lets you enjoy 360 Reality Audio.

MQA™

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

Bluetooth® and aptX™ HD

Connect wirelessly with Bluetooth and you’re ready to go. aptX™ HD audio compatibility is available.
