The price is 400,000 yen! Walkman’s flagship model “NW-WM1ZM2” that brings together analog and digital high-quality sound technology

In addition to circuit design, pursuing high sound quality from capacitors and solder

Sony will release the flagship model Walkman WM1 series “NW-WM1ZM2” from March 25 as the “Signature Series” that brings together the analog and digital high-quality sound technologies of the company.

At the same time, “NW-WM1AM2”, which pursues sound quality, will be released at the same time from the same series.

All prices are open prices. The estimated actual price is around 400,000 yen for the “NW-WM1ZM2” (256GB) and around 160,000 yen for the “NW-WM1AM2” (128GB).

Both models are equipped with a full digital amplifier “S-Master HX” for DSD native playback (* 1) (maximum 11.2MHz) and linear PCM (maximum 384kHz / 32bit) high-resolution audio (high-resolution) sound source playback. It corresponds.

In addition, it is equipped with a JEITA unified standard φ4.4 mm headphone balance terminal. The chassis is made of carefully selected materials with few impurities to significantly reduce the resistance of the chassis, and high-quality solder is used for all joints.

In addition, the power supply has been strengthened by installing FTCAP3 (newly developed polymer capacitor) in all the bypass capacitors of the power supply of the audio block, and high sound quality has been thoroughly pursued.

In addition, Android is newly installed, streaming playback is possible by supporting Wi-Fi connection, and a new “DSD remastering engine” that converts all PCM sound sources to DSD signals equivalent to 11.2MHz is also installed.

In addition, a large 5.0-inch display and USB Type-C cable support have realized high operability and convenience.

The packaging of this product is said to have achieved zero plastic usage (* 2) for individual packaging.

* 1 Valid only when playing W. music with a wired connection. W. Not valid for playback other than music or for wireless listening (when connected to Bluetooth®). DSD native playback is supported only when balanced connection is used. When unbalanced connection, conversion to linear PCM and playback.
* 2 Excludes materials used for coating and adhesion.

Explains carefully selected parts and design structure that realize high sound quality

Pursuing high sound quality by significantly reducing chassis resistance

“NW-WM1ZM2” adopts a total machined oxygen-free copper chassis with a purity of about 99.99%, which reduces impurities to about 1/4 compared to the conventional one (* 3). By further reducing the resistance value by improving the purity of oxygen-free copper, we have realized a clear treble with a long stretch and a clearer and more powerful bass range.

“NW-WM1AM2” adopts a fully machined aluminum chassis for the housing. In addition to achieving both low impedance and high rigidity by using integrated aluminum for the material of the rear cover, the company explained that it was able to obtain sound quality with a sense of stretch and transparency.

Achieves clear and powerful bass by strengthening the power supply

Introduced FTCAP3 (newly developed polymer capacitor) with tuned internal structure for all bypass capacitors of the power supply of the audio block. Utilizing the development know-how of stationary audio equipment, we improved the sound quality by improving the vibration resistance.

In addition, the newly developed large-capacity solid polymer capacitor prevents a sudden voltage drop and enables accurate signal output, contributing to clear and powerful bass expression.

Enhanced audio line

Lead-free high-quality solder is used for all joints. In addition, high-quality solder with gold added is used for the soldered part of the headphone output and the cream solder of the board to enhance the reproduction, spread, and localization of fine sound.

In addition, the internal cable that connects the amplifier of “NW-WM1ZM2” to the headphones uses a thick cable with a 4-core Braid structure developed in cooperation with KIMBER KABLE.

Improved sound quality with original technology such as “DSD remastering engine”

This time, a new “DSD remastering engine” that converts all PCM sound sources into DSD signals equivalent to 11.2MHz without damaging the amount of information in the original data is installed. Since it can be turned ON / OFF, it can be switched according to your preference.

It is also equipped with “DSEE Ultimate,” which uses AI (artificial intelligence) technology that learns a huge amount of music data to analyze music in real time and optimally upscale compressed sound sources to high-resolution sound quality. By expanding the bits and increasing the sampling frequency, it is possible to upscale up to the equivalent of 192kHz / 32bit.

By using AI technology, the type of song is automatically determined, and high reproducibility is achieved not only for high frequencies but also for fine sounds.

In addition, the evolution of the AI ​​algorithm has improved the upscaling performance of CD sound quality equivalent sound sources (44.1kHz and 48kHz / 16bit).
