ZX707 Walkman® ZX Series

Upgraded components for an enhanced sound
We've upgraded many of the internal components so that the 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 Capacitors
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-ZX707used to strengthen the power supply of the am unbalanced output, enhancing low-range reperformance for a more expansive listening experience.
