Astell&Kern A&norma SR35 Digital Audio Player (Open Box)

Astell&Kern SR35 Digital Audio Player - 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 4.4mm 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 is known so well for.The ultra compact SR35 features 20 hours of continuous playback, while supporting Quad DACs 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.

Quad-DAC Mode for True 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 the 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 SRN 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 Astell&Kern SR35 supports Native DSD256 and PCM playback of up to 32bit/384kHz 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 in-house 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 OP AMP selection to component placement and circuit design.

Moreover, in order to reliable operate different impedance output sources, the current handling capacity at the output end is increased to maximize the performance of various devices with one SR35.

2-Step Gain Mode for the Perfect Hi-Fi Experience

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 2-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 6Vrms from the balanced connections, driving high-impedance headphones has never been easier.

New Experience, New User Interface

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 and 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.

Roon Ready and MQA Support for Hi-Fi Fans

Roon Ready is a service for Hi-Fi fans who wish to play the best Hi-Fi sound without compromise on various devices through network systems.

Roon Ready, available on some premium audio products, now comes with the A&norma series for the first time, offering you a SR35-controlled network audio system to deliver the best sound quality.

Additionally, it supports the full decoder of MQA 8X so that the SR35 can play and stream Hi-Fi MQA sound natively, true to the concept of A&norma that plays original sounds anywhere and at any time.
