    Sony justifies the outrageous price tag of the NW-ZX707 by using high-end components. Things start with the large, solid high-polymer capacitor that acts as a battery assist for the amplifier block. Besides offering low resistance and large capacitance, it also aids in the product’s ability to output clear signals, according to Sony. Meanwhile, all of the bypass capacitors on the NW-ZX707 are also of the FT CAP3 type, which is a Sony parlance for high polymer capacitors. To supply the optimum balanced output signal from the digital amp, the NW-ZX707 uses a larger 8 mm coil for the lowpass (LC) filter.

    In addition to these features, the Walkman uses low resistance Oxygen-Free Copper (OFC) for the internal headphone connector. The device also uses two compact low-phase noise crystal oscillators that aid in excellent instrumental separation and open sound reproduction. Sony has judiciously used gold across the internals of the NW-ZX707, including its solder and reflow solder elements, to further improve sound localization. The PCB of the NW-ZX707 has been designed to keep digital interference to the minimum by separating the audio black from the digital block.

    #Sound processing done right

    For audiophiles, one of the most important reasons for choosing the NW-ZX707 over other options is its capability to perform native DSD (Direct Stream Digital) decoding. This feature ensures the NW-ZX707 can transform standard MP3 or PCM audio to the ultra-high frequency 11.2 Mhz DSD audio stream. This lends the sound a distinct analog character that many audiophiles have come to love.

    The NW-ZX707 also gets Sony’s proprietary digital music processing technologies, including the DSEE Ultimate technology, developed in-house to restore compressed music files to the quality of a CD by interpolating sound algorithms. DSEE Ultimate is Sony’s most advanced technology, which incorporates artificial intelligence to upscale compressed audio files to near-Hi-Res Audio quality. It also has a balanced headphone output that can deliver a more detailed and immersive listening experience.

    Another reason audiophiles have come to appreciate the NW-ZX707 is something called the vinyl processor that lends the unmistakable character of vinyl discs back to their digital tracks. In addition to this, the device also gets a DC Phase Linearizer that gives users six phase character settings to choose from and select between multiple analog-like sound options. The Sony NW-ZX707 can last up to 25 hours of 44.1 kHz FLAC playback, up to 23 hours of 96 kHz FLAC High-Resolution Audio playback, and up to 22 hours with streaming music apps.
