For the first time in the A&norma series, the SR35 deploys the CS43198 DAC from Cirrus Logic, in Quad DAC configuration. A very well-received DAC praised for its outstanding spatial sense and resolution.
In addition to this, a new design of audio circuit has been implemented, incorporating Astell&kern’s unique technologies along with the Quad DAC and our patented TERATON ALPHA technology for outstanding advancement in the dynamics, sense of space, resolution, and level of separation. Furthermore, our latest technologically advanced amplification circuitry, which was only available in our flagship products has now been incorporated to the SR35, boasting a dramatically improved and industry leading SNR of 130dB.
A Dual/Quad DAC Switching mode is offered enabling users to adjust and improve power management efficiency, further improving 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 allowing you to enjoy true Hi-Fi sound without any restriction and free from distortion.
Astell&Kern's brand philosophy - refusing to overlook even the smallest differences in sound quality - has been recognized by numerous media and audiophiles through
our multiple releases of premium audio players that combine innovative circuits and amplifier technologies.
The SR35 is equipped with New generation AMP technology that was applied to the A&ultima line so that A&norma users can also enjoy the highest level of sound provided by the A&ultima line with this exclusive inhouse technology.
The new generation AMP technology applied to the SR35 is Astell&Kern's unique amplifier design that effectively improves noise reduction at high power output.
With this new technology, the SR35 contains the same amplifier design as the latest A&ultima and A&futura products, completely transforming into an amplifier design worthy of premium audio, from OPAMP selection to component placement and circuit design.
Moreover, in order to reliably operate different impedance output sources, the current handling capability at the output end is increased
to maximize the performance of various devices with one SR35.
For seamless use of sensitive IEMs and hard to drive headphones, a device must provide suitable output, respective of the connected device’s specification.
The SR35 supports a 2-step Gain Level mode to create the perfect match for a wide range of headphones and IEMs, maintaining optimal sound output.
The two-step gain setting with "Normal Gain" and "High Gain" modes can generate a high current output to create a powerful sound and excellent driver control.
With up to 6 Vrms from the balanced connections, driving high-impedance headphones has never been easier.
The SR35 provides premium-class audio specifications and genuine
Hi-Fi sound by Astell&Kern.
Along with the core value of A&norma series that seeks to provide unlimited Hi-Fi audio anywhere and at any time, we offer you the best portability in the digital audio player market, with a class leading long playtime and powerful output.
The compact size of the SR35 fits easily in your pocket and weighing in at only 184g is light enough to carry without any inconvenience.
With a maximum of 20-hour continuous playtime, you can enjoy music without a recharge all day long.
The SR35 is the perfect companion that you can use for long-haul flights as well as full days at work and vacations, guaranteeing you Hi-Fi sound anywhere, anytime.
The SR35 comes with a redesigned Crimson-themed UI/UX transforming into a "true music player" for users to deeply connect with their music listening experience.
The new UI/UX is designed so that users can quickly browse music categories and re-discover songs within their music library.
We 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.
Immerse yourself in music with the new UI/UX.
