The gold-plated NW-WM1Z Walkman from Sony is a high-resolution digital music player featuring audiophile-quality playback with Bluetooth compatibility, 256GB of internal storage, and a solid-sculpted oxygen-free copper body. The Walkman uses the S-Master HX digital amplifier, which was developed to provide high-resolution playback utilizing a mastering-quality digital amplifier for a wide frequency response, while minimizing distortion and noise.
Other enhancements include four wire braided cables engineered with KIMBER KABLE, FT CAP (high-polymer capacitor) that works to regulate power flow, and DSEE HX upscaling technology, which uses an algorithm to analyze your music and replace any lost information when needed. Additionally, the NW-WM1Z utilizes a DC Phase Linearizer that works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match six phase characteristics of various types of analog amplifier to deliver a purer, more analog-like sound.
The player supports music files up to 384 kHz/32-bit rate and DSD Native playback (11.2 MHz) and is compatible with the following formats; AIFF, WAV, ALAC, MP3, WMA, AAC, and FLAC. Additional storage is available via optional microSD card. The built-in rechargeable battery offers up to 30 hours of high-resolution playback (FLAC 96 kHz/24-bit) and 33 hours of MP3 playback (128 kbps). The Walkman ships with a USB cable and a leather case.
