Astell&Kern A&norma SR35 Hi-Res Audio Player in Black

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 is 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 patented TERATON ALPHA technology for outstanding advancement in the dynamics, sense of space, resolution, and the level of separation. Furthermore, the latest technologically advanced amplification circuitry, which was only available in AK flagship products has now been incorporated into the SR35, boasting a dramatically improved and industry-leading SRN of 130dB.

A Dual/Quad DAC Switching mode is offered to enable 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 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 recognised by numerous media and audiophiles through 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 reliably 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.

The SR35 provides premium-class audio specifications and genuine Hi-Fi sound by Astell&Kern.

Along with the core value of the A&norma series that seeks to provide unlimited Hi-Fi audio anywhere and at any time, Astell & Kern offers 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.
