Sony's New Premium Walkmans Chase Cleaner Sound Through Hardware
Sony has announced three new premium Walkman digital media players, the NW-ZX900, NW-WM1AM3 and NW-WM1ZM3. The Verge
The NW-ZX900 is priced at $1,899.99. The NW-WM1AM3 is priced at $2,999.99. The gold-plated NW-WM1ZM3 is priced at $5,899. The Verge
In Canada, the NW-WM1ZM3 carries a suggested retail price of $8,259.99. The NW-WM1ZM3 is available for pre-order from Sony, B&H and Crutchfield. TechPowerUp
All three models use the same digital starting point. They use Sony's DSD Remastering Engine, which converts standard PCM audio, the normal format for CDs and most digital files, into an 11.2MHz DSD stream, a much higher-rate format. All three also have gold plating on the rear chassis, intended to reduce interference and lower noise.
The two WM1 models add extra work on wiring and power. Both use hand-soldered oxygen-free copper wiring, meaning high-purity copper, with upgraded power circuitry. Both include a milled OFC block that keeps the digital circuits physically separate from the analog circuits that produce sound.
The WM1ZM3 takes that materials approach to the whole body. Its entire chassis is made of OFC and then gold-plated. The WM1AM3 is nearly identical, minus the gold shell.
For buyers comparing the three, the common thread is noise control rather than feature count. Upsampling to 11.2MHz DSD, rear-chassis plating, isolated power rails and physical separation between digital and analog parts all aim at the same problem. Keep switching noise out of the output stage. Engineers who work on mixed-signal layout will recognize that priority list. Power integrity and shielding often matter most once decoding is settled.
The broader context here is segmentation by construction. Sony has held the remastering architecture and rear-chassis treatment constant across the three players. Price then scales with metals, solder work and power design. The ZX900 gets the shared platform. The WM1 pair adds OFC wiring, revised regulation and the milled isolation block. The ZM3 adds the full OFC, gold-plated enclosure. It is a straightforward ladder. You pay for lower impedance paths, heavier isolation and more labor-intensive assembly.
In my view, that choice will read as disciplined or indulgent depending on where you sit. For listeners who keep a dedicated player for careful, file-based playback, supply noise, ground contamination and EMI pickup are audible variables. Those are the parameters Sony is addressing. Worth flagging, none of this guarantees audibility in every chain or with every transducer. It does lower the electrical noise floor the analog stage has to work against, which is the correct place to spend effort in a portable high-resolution design.
What this enables, if the implementation holds, is a portable chain built around purity rather than consolidation. A dedicated media player can devote volume, mass and power budget to regulation, isolation and chassis design. Sony is using that freedom directly, with copper, gold and physical separation doing work that software alone cannot.
