The use of the S-Master HX Hi-Res audio amplifier allows for compatibility with the Native DSD format, providing balanced high-power output. It helps reduce distortion and noise across a wide range of frequencies. Thanks to high-quality PCM conversion, DSD audio formats up to 11.2 MHz are possible.

When playing back 360-Reality-Audio-supported tracks with the ZX707 Walkman, music comes alive all around you, centering you in an immersive experience that makes it feel like you're at a live concert, or in the recording studio itself with the artist.

Get closer to the sound of the original recording with support for the following sound processing technologies:

• Hi-Res Audio: Reproduces music better than 24-bit 96 kHz, for better-than-CD audio
• DSD: Native 11.2 MHz DSD when using balanced headphones, and support for 32-bit / 384 kHz PCM
• Hi-Res Audio Wireless with LDAC: Hi-Res without wires, thanks to the LDAC codec that has 3 times the bitrate of standard Bluetooth
• MQA: Support for the playback of high-end MQA files
• aptX HD: Works with aptX HD audio over Bluetooth

With DSEE Ultimate using Edge-AI, your digital music is upscaled in real time to restore acoustic subtleties and dynamic range, giving you a more complete listening experience.

The warmth heard when playing records is added to your digital files for a more authentic sound by reproducing the low-frequency resonance, tone-arm resistance, and surface noise of vinyl.

The DC Phase Linearizer works to effectively replicate a variety of sonic signatures. Digital signal processing is applied to match phase characteristics of various types of analog amplifier to output a purer, more analoglike sound. You can choose from 6 phase character settings.

The rigid aluminum chassis is designed to provide physical rigidity and a resistance to electrical noise and other interference, resulting in stable, high-quality audio. Housed inside this frame is a host of high-quality components that are engineered to enrich the music you hear through the ZX707 Walkman.

• Large solid high-polymer capacitor: provides significant power to prevent sudden falls in voltage, resulting in clear and accurate bass and vocals
• FT CAP3: these bypass capacitors help deliver a smoother, wider, and more transparent sound with a tighter bass
• Large 8mm coil: used as the L-C filter, this coil helps achieve lower distortion and resistance that in turn improves resolution across all frequencies
• OFC (oxygen-free copper) block: Strengthens digital ground and shields the digital block element from noise, resulting in a clearer sound
• Film capacitor: delivers voltage with a linear response across frequencies, resulting in reduced distortion and noise.
• Fine sound resistor: Ensures the even and effective distribution of power to the circuit components for consistent sound quality
• OFC cable: offers low distortion and improved channel separation when using headphones.
• Crystal oscillators: Two low-phase-noise oscillators for precise clock stability at sampling rates of 44.1 and 48 kHz. This results in reduced noise and clearer sound
• Gold-infused solder: This is used to connect the circuit of the NW-ZX700 to the battery, using the exceptional conductivity of gold to minimize signal loss for a clearer sound and vocals
• Low-dielectric circuit board: using low and dielectric material for accurate signal transmission, while via holes are filled with copper reduces impedance. resulting in a wider, clearer, and brighter sound
• Optimized circuit-board layout: optimized to ensure sound is unaffected by digital interference

Two analog-style user interfaces are included to give the ZX707 a vintage touch. The volume UI provides a digital representation of an analog volume knob. The Cassette Tape UI is a playful nod to the Walkman's heritage. This UI and screensaver features the image of a cassette tape that will vary based on the codec of the music you're listening to.
