Hi-Fi Sound on-the-go

The A&norma series was created to enjoy the premium sounds of Astell&Kern in a portable size with best in class specifications.
SR25 MKII, the previous model in the series, was loved by audio enthusiasts and those just starting their personal audio journey thanks to its portable size and powerful Hi-Fi sound through a 4.4-mm balanced jack.

The A&norma SR35 inherits these strengths while applying the amplifier and audio design that was applied to Astell&Kern's premium products to deliver the authentic sound quality that Astell&Kern are so well known for. The ultra compact SR35 features 20 hours of continuous playback, while supporting Quad DAC and two-step Gain control, and the A&norma line's first introduction of New Generation Amp technology with Astell&Kern's long-standing know-how for an even more delicate and clear Hi-Fi sound at higher output.

We have also applied our new UI/UX with improved visuals and usability to the SR35 for a more immersive music experience. In addition to this the SR35 is equipped with Roon Ready and MQA full decoder support to further enhance the performance of our A&norma line.

Hi-Fi Sound

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.

The Essence of Astell&Kern Technology
– Equipped with New generation AMP

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.
