Sony WM1ZM2 Walkman Signature Series

Purer materials for a purer sound
Despite oxygen-free copper (OFC) being notoriously difficult to machine process, the WM1ZM2 features a gold-plated OFC chassis – just like its predecessor. This time though, OFC purity has been upgraded to 99.99% (four nines), offering even greater benefits in terms of audio quality and high rigidity. Bass notes are clear and powerful, the atmosphere is more expansive, and mid to high range sounds linger beautifully.

KIMBER KABLE® 

The wiring material from the amp base to the balanced headphone jack has been upgraded to thick KIMBER KABLE®, just like on the flagship DMP-Z1 music player. This helps to shut out external noise, transmit high quality audio signals, and achieve powerful and smooth sound quality.

Pure Listening Indulgence
Part of the Signature Series, the WM1ZM2 sets a new benchmark in pure sound quality and listening sophistication. Crafted with fine materials and meticulous attention to detail, and offering the ease of downloading and streaming music, this is audio at its most indulgent.

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 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, it has helped to improve sound expression and create a smoother sound, with a wider sound space, more transparency, and tighter bass.

OFC milled block
An OFC 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.

Crystal oscillators
Two compact low-phase-noise crystal oscillators ensure precision clock stability at sampling rate multiples of 44.1kHz and 48kHz. The crystal electrode piece is formed with gold vapour deposition for enhanced electric characteristics and improved instrumental separation. This helps remove a veil and reduce noise to realise clear, open sound reproduction.

Fine Sound Register
The surface mounted Fine Sound Register ensures even, effective distribution of power to the circuit components, for consistent sound quality.

Optimised circuit board layout
By dividing the Audio block (highlighted in red) and the Power/Digital block (in blue), the circuit board layout has been optimised to ensure sound quality is unaffected by digital interference.
