Sony Electronics Inc. today announced new premium Walkman digital media players - NW-WM1ZM3, NW-WM1AM3, and NW-ZX900. Designed for music enthusiasts and audiophiles, the new Walkman models are engineered to deliver exceptional sound and incorporate a wealth of premium audio components throughout their design. The NW-WM1ZM3 and NW-WM1AM3 bring together Sony's most advanced audio technologies, including key components made from oxygen-free copper, for uncompromising sound quality.
The WM1 Series is designed to convey the artist's original intent, delivering detailed, high-resolution sound. The NW-ZX900 inherits many of the same premium audio components used in Sony's flagship model, delivering exceptional sound quality with a sleek design. Class-leading components deliver the highest possible sonic performance.
The NW-WM1ZM3 is built around a precision-machined, gold-plated oxygen-free copper (OFC) chassis, engineered specifically to further elevate the sound quality of this flagship model. It features a 99.99% (4N) purity OFC main chassis and an OFC rear chassis. These are secured with screws featuring a low-resistance gold-plated treatment applied exclusively for this model, providing a stable ground connection that delivers powerful bass, an expansive soundstage, and smooth, extended high frequencies.
Thick KIMBER KABLE wiring, inherited from Sony's DMP-Z1, further reduces noise and preserves signal integrity for rich, detailed sound. The NW-WM1AM3 and NW-ZX900 adopt a similar design philosophy, combining an aluminium-alloy main chassis with a gold-plated OFC rear chassis to enhance rigidity and sound quality. The NW-WM1ZM3 and NW-WM1AM3 further evolve Sony's premium power circuitry with a significant enhancement to the power supply architecture: the previous single large solid high-polymer capacitor has been replaced by dual large solid high-polymer capacitors.
Together with hand-soldered OFC wiring, this advanced configuration helps provide cleaner, more stable power with minimal interference. A larger, high-purity 4N copper coil is used in the L-C filter to optimize the balanced output signal from the digital amplifier. Its flat conductive wire reduces resistance and distortion, enhancing clarity and detail across the frequency range.
An OFC milled block covering the digital section also strengthens the digital ground. With approximately 34% greater mass than the previous model, it helps further reduce noise and reproduce sound with greater clarity and definition. The NW-ZX900 also benefits from new premium parts, including an ultra-low noise LDO regulator and cryogenic components.
