In short, the new Sony NW-WM1AM2 premium audio player has almost all the technical characteristics of the Sony NW-WM1ZM2, modulo two major differences: an aluminum chassis and not a gold-plated copper one, a low-resistance OFC cable for connect the base of the amp to the balanced headphone jack and a storage memory of 128 GB against 256 gigabytes.
For the rest, there is a 5'' (12.7 cm) 720p HD LCD touch screen and Wi-Fi compatibility for easy access to the main music platforms (streaming and downloading) or personal audio libraries. The operating system is Android 11.0.
Sony NW-WM1AM2, S-Master HX and FT CAP3 Capacitors
Compatible with balanced connection and Hi-Res Audio format, the Sony NW-WM1AM2 incorporates the latest audio technologies available, starting with Sony's S-Master HX digital amplification, independently developed for Walkmans. It contains several FT CAP3 (High Capacity Electrolytic Capacitor) capacitors as well as a large solid electrolyte capacitor with large capacitance and low resistance.
Sony NW-WM1AM2, DSD remastering engine
Also noteworthy, a dual clock and a Fine Sound Register (for controlled current distribution to all components for consistent audio quality), as well as a DSD remastering engine to resample PCM audio (Pulse Code Modulation) in DSD format. We should mention in passing the presence of DSEE Ultimate technology, which uses artificial intelligence to adapt the audio frequency and the signal rate in real time for an always optimized sound quality. Also note that the autonomy of the device displays 40 uninterrupted hours in Hi-Res Audio playback in Flac format (96 kHz).
Available from April 2022. Indicative price: 1,400 euros.
