Gold-Plated Copper Chassis and $5,900 Price Tag: Sony Unveils New-Gen Audiophile Walkman Lineup
Sony Electronics is making a massive statement in portable high-fidelity audio. The Japanese manufacturer has officially introduced the next generation of its legendary Walkman digital media player lineup with three flagship models: the NW-WM1ZM3, NW-WM1AM3, and NW-ZX900.
Leading this prestigious collection is the extraordinary NW-WM1ZM3 Signature Series, commanding an eye-watering price of $5,899. To justify this stratospheric tier, Sony engineers precision-machined a solid oxygen-free copper (OFC) chassis with 99.99% purity, fully electroplated with pure gold.
This massive structural foundation brings the player to a substantial 670 grams to eliminate chassis resonance. Internal wiring features custom four-wire braided Kimber Kable, directly inherited from the reference DMP-Z1 digital audio system.
Positioned just below the flagship, the NW-WM1AM3 retails at $2,999, combining a precision-milled aluminum alloy frame with a gold-plated oxygen-free copper rear panel for rigid acoustic dampening. Meanwhile, the NW-ZX900 delivers a sleeker, travel-friendly chassis at $1,899 while retaining the core audio components of the WM1 series.

Proprietary S-Master HX Amplification and Precision Audio Architecture
All three players share Sony's refined digital audio DNA, driven by the proprietary S-Master HX digital amplifier. The motherboard integrates ultra-low phase noise quartz oscillators with gold vapor deposition, paired with low dielectric constant circuit boards.
Advanced digital signal processing is handled by Sony's DSEE Ultimate AI upscaling and DSD Remastering engines, reviving micro-details and acoustic texture in real time across any digital stream.
On the interface side, the NW-WM1ZM3 and NW-WM1AM3 feature a sharp 5.5-inch Full HD 1080p touchscreen, while the NW-ZX900 carries a compact 5-inch display. All three run on Android 16 with native Wi-Fi connectivity, allowing seamless access to lossless streaming services like Qobuz, Tidal, and Apple Music.
Analog connectivity includes a standard 3.5mm unbalanced jack alongside a dedicated 4.4mm balanced Pentaconn output. High-resolution wireless streaming is fully supported via LDAC, Qualcomm aptX Adaptive, and LC3 codecs.
My Take: An Uncompromising Masterpiece for Pure Portable Audio
Seeing Sony continue to cherish the legendary Walkman heritage with such uncompromising acoustic dedication commands genuine respect. Even if a $6,000 player made of gold-plated solid copper caters strictly to dedicated collectors, these mechanical marvels prove that pristine audio still matters in an era dominated by compressed mobile streaming.
While the mainstream audience focuses entirely on wireless headsets and portable audio, these media players remind us what uncompromised fidelity truly delivers. For serious audiophiles seeking reference-grade listening on the go, this is the ultimate portable holy grail.
