    Sony trots out new Hi-Res Walkman: NW-ZX2
    Sony’s legendary Walkman family has gained a new flagship player, which is made for serious music lovers.
    The High-Resolution Walkman NW-ZX2 puts the refinement of Hi-Res Audio right in your pocket – taking you ‘beyond CD quality’ for an extra-special listening experience, while you’re out and about.

    Sony’s S-Master HX full digital amplifier keeps audio signal processing entirely in the digital domain to support pristine playback of Hi-Res sound. This technology accurately processes massive amounts of wide-bandwidth audio data while minimising noise and distortion.

    DSEE HX processing recreates high-frequency musical information that’s lost in compressed sound files. CD and MP3 sources are upscaled, expanding sampling frequency and bit-depth beyond their original values to near Hi-Res quality (corresponding to 192 kHz/24-bit audio).

    The player’s frame is milled from solid aluminium alloy for ultimate rigidity, while internal use of gold-plated copper plate reduces electrical impedance to assist with overall sound quality.

    Every stage of the audio pathway is upgraded with extensive use of thick-film copper-layer PCBs, OFC (Oxygen Free Copper) cables and high purity lead-free solder. Overall sound quality is further enhanced by use of carefully-selected components including coils, MELF type resistors and film condensers. No less than seven extra-large condensers, ‘OS-CON’, maintain frequency response and minimise noise at the output stage.


    One digital clock source is replaced by two, with dedicated crystal oscillators for 44.1/88.2/176.4 kHz (CD/DSD) and 48/96/192 kHz sources respectively.

    The NW-ZX2 is the first ever Walkman that supports the efficient LDAC codec. This new audio technology from Sony lets you enjoy high quality wireless audio via Bluetooth, transmitting data three times more efficiently than previous Bluetooth connections. One-touch pairing with NFC makes wireless connection between Walkman and other devices instant and effortless.

    There’s also a generous 128GB of internal storage, expandable to 256GB with an optional microSD card, which should give capacity for around 1700 songs stored as Hi-Res Audio files (at 150MB/song). In addition, listening time is boosted by a new high capacity Li-ion battery that boosts playback time to as long as 60hrs (MP3 files) from a single charge.

    Dual-band (2.4/5 GHz) Wi-Fi compatibility lets you enjoy Hi-Res music stored on your DLNA home network, free of electrical interference. The player also supports a USB audio connection function for direct, jitter-free digital connection to portable headphone amps and USB DAC amps.

    The new Walkman NW-ZX2 with High-Resolution Audio from Sony is on sale in Europe from Spring 2015
