Hi-Fi Sound On-The-Go
The A&norma series is designed to offer Astell&Kern’s premium sound in a compact size with premium features.
The SR25 MKII, the previous model in the series, was loved by audio enthusiasts and beginners alike thanks to its portable size and fantastic sound. The Astell&Kern SR35 inherits these strengths while utilizing the same proven amplifier and audio design used in Astell&Kern’s premium products.
The ultra-compact SR35 offers 20 hours of continuous playback, utilizes a premium Quad DAC and two-stage gain control, as well as a new generation of amplifiers.
The SR35 also utilizes the latest user interface with improved graphics and usability to deliver a more immersive music experience. In addition, this DAC is equipped with Roon Ready and MQA full decoder support to further enhance the performance of the A&norma line.
Quad DAC mode for true Hi-Fi sound
For the first time in the A&norma series, the SR35 utilizes Cirrus Logic’s CS43198 DAC in Quad DAC configuration.
In addition, a new audio circuit design has been implemented that utilizes Astell&Kern’s unique technologies together with the Quad DAC and patented TERATON ALPHA technology for outstanding dynamics, spaciousness, resolution and separation.
In addition, the latest amplification circuitry from A&K’s flagship products has been implemented.
A dual/quad DAC switching mode is offered, allowing users to customize and improve power management efficiency and further enhance the long continuous playtime, a core feature of the A&norma series.
The SR35 supports native DSD256 and PCM playback of up to 32-bit/384 kHz, enabling true hi-fi sound without limitations and free from distortion.
New Generation AMP
Astell&Kern’s commitment to uncompromising sound quality is at the forefront of their brand philosophy, and the SR35 is a testament to their dedication. The utilization of New Generation AMP technology, previously featured in the A&ultima line, extends the highest level of sound quality to A&norma users.
This exclusive in-house technology represents a unique amplifier design by Astell&Kern, with a primary focus on enhancing noise reduction at high power output. The incorporation of this new generation AMP technology positions the SR35 alongside the latest A&ultima and A&futura products, ensuring a premium audio experience.
The transformation of the SR35’s amplifier design encompasses various elements, from meticulous OPAMP selection to precise component placement and circuit design. These considerations collectively contribute to elevating the SR35 into a realm of audio quality befitting premium standards.
Furthermore, the SR35 is engineered to reliably operate with different impedance output sources. The enhancement of current handling capability at the output end not only ensures optimal performance but also allows the SR35 to accommodate a variety of devices seamlessly. This adaptability underscores the versatility of the SR35, making it a comprehensive solution for audiophiles seeking a high-quality audio experience across diverse devices.
2-Step Gain Mode for the Perfect Hi-Fi Experience
The SR35 demonstrates a keen understanding of the diverse needs of audiophiles, ensuring a seamless experience with both sensitive IEMs and hard-to-drive headphones. Recognizing that different devices have unique specifications, Astell&Kern has incorporated features to provide suitable output for a wide range of headphones and IEMs.
One key feature is the 2-step Gain Level mode, offering flexibility for users to achieve an optimal match for their connected devices. The “Normal Gain” mode is designed for sensitive IEMs, providing a balanced and suitable output to preserve sound quality. On the other hand, the “High Gain” mode is tailored for hard-to-drive headphones, delivering a high current output that results in powerful sound and precise driver control.
The inclusion of these two gain settings caters to the varied impedance and sensitivity levels found in different audio equipment. This adaptability allows users to customize the SR35’s output according to the specific requirements of their headphones or IEMs, ensuring an ideal listening experience.
Moreover, the SR35 boasts an impressive output of up to 6 Vrms from its balanced connections. This high output capability is particularly beneficial for driving high-impedance headphones, providing the necessary power to fully unleash their potential. By offering a robust output through balanced connections, the SR35 makes it easier for users to enjoy premium audio quality even with demanding headphones that traditionally require more power to deliver an optimal sound experience.

Crimson User Interface
The SR35 comes with a Crimson-themed UI/UX, which makes this a “true music player” for users to deeply connect with their music.
The new UI/UX is designed so that users can quickly browse music categories and re-discover songs within their music library.
Astell&Kern has also added an easy album art search function so that users can re-discover the joy of viewing and interacting with music album art whilst listening to their music.
The crimson theme focuses on edge, simplicity, and dark mode keywords. The color theme of black with red highlights lowers visual fatigue and offers intuitive user experiences, and many other improvements were made to the device’s user-friendliness of app service, artist view, album sorting, and the album art search function.
