DELVE DEEPER INTO YOUR MUSIC WITH THE BRAND-NEW SR35
Astell&Kern needs no introduction; it is an innovative brand known for incorporating some of the best-in-class technologies into its product line-up. Their A&norma series had introduced some of the most celebrated DAPs like the SR15, SR25, and SR25 MKII. The previous model in the series, the SR25 MKII, was adored by audiophiles because of its portable size and exceptional sonic abilities. This time around Astell&Kern has broken all barriers in terms of technology and developed the all-new and improved SR35. The Astell&Kern A&norma SR35 inherits the same strengths while applying the amplifier and audio design found on Astell&Kern's premium products to deliver the authentic sound quality that Astell&Kern is 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 authentic and true-to-life HiFi sound at higher output. Astell&Kern engineers have also applied a new UI/UX with improved visuals and usability to the SR35 for a more immersive music listening experience. Moreover, the SR35 has Roon Ready and MQA full decoder compatibility to improve the functionality of the A&norma series of DAPs even more. The Astell&Kern A&norma SR35 is a technological marvel that will go down and create history!




UNLOCK YOUR PATH TO HIFI SOUND WITH THE QUAD DAC ARCHITECTURE
For the first time in the A&norma series, the SR35 deploys the CS43198 DAC from Cirrus Logic in Quad DAC configuration. Moreover, a new design of audio circuits has been established, including the Quad DAC and Astell&Kern's innovative technologies. Astell&Kern's patented TERATON ALPHA technology has been implemented for outstanding advancement in the dynamics, sense of space, resolution, and level of separation. Furthermore, their latest technologically advanced amplification circuitry has been incorporated into the SR35, boasting a dramatically improved and industry-leading SNR of 130dB. A Dual/Quad DAC Switching mode allows you to adjust power management efficiency and improve the long continuous playtime, a core feature of the A&norma series. The Astell&Kern A&norma SR35 supports Native DSD256 and PCM playback of up to 32 bit/384 kHz allowing you to enjoy HiFi sound without restriction and free from distortion. Unlock your path to HiFi sound with the brand-new SR35!

EQUIPPED WITH NEW GENERATION AMP TECHNOLOGY AND TWO-STEP GAIN MODE
Astell&Kern has been known to innovate and improvise with their AMP technologies and innovative circuit boards. Astell&Kern engineers pay equal importance to the amplification technology and the DAC architecture. The Astell&Kern A&norma SR35 hosts a 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. The Astell&Kern A&norma 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" and "High Gain'' modes can generate a high current 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 so responsive.

FEATURES THE HALLMARK OF A&K AUDIO TECHNOLOGIES - THE TERATON ALPHA
TERATON ALPHA, Astell&Kern’s in-house ultimate sound solution, makes it possible to realise high output and Quad DAC for a wide variety of earphones and headphones whilst maintaining long playtime with minimal noise. Astell&Kern improved the A&norma series using audio technology from other Astell&Kern products lauded by innumerable audio enthusiasts and media critics. The TERATON ALPHA technology gained success through years of technical research and development. TERATON ALPHA, engineered through extensive research, is Astell&Kern's unique technology designed to produce audio playback that is as close to the original recording through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface.



A NEW DEFINITION OF WIRELESS MUSIC PLAYBACK WITH BLUETOOTH AND WIFI SUPPORT
The Astell&Kern A&norma SR35 is equipped with Bluetooth v5.0 with support for Bluetooth codecs like LDAC and Qualcomm® aptX™ HD. It also offers dual-band (2.4/5Ghz) WiFi support providing uninterrupted and enhanced network performance, allowing you to enjoy HiFi music through various streaming and Roon Ready services. The Astell&Kern A&norma SR35 allows wireless music playback from a smartphone or any other Bluetooth-enabled device through BT Sink functionality. BT Sink function connects the SR35 to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker. Music from an external device, such as a smartphone, can now be played back in high-quality on the SR35 using the BT Sink function. ReplayGain, which adjusts sound sources with different volumes to a sufficient level, has been applied to the SR35. Music file management is now possible with a cableless, wireless solution. The new AK File Drop function in the SR35 makes file transfers more convenient. Using AK File Drop, you can transfer files wirelessly through a PC, smartphone, or FTP program located on the same network.
NOTE: ReplayGain supports up to 24-bit/192 kHz sound sources.



ENJOY A CONTINUOUS PLAYTIME OF UP TO 20 HOURS
The Astell&Kern A&norma SR35 hosts a 3,150mAh 3.7V Li-Polymer battery offering 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.
NOTE: The 20 hours of battery life is tested with Standard : FLAC, 16bit, 44.1kHz, Normal Gain, Unbalanced, Vol.50, LCD Off, Dual DAC Mode.

ROON READY WITH MQA SUPPORT AND DAC FILTERS
Roon Ready is a service for HiFi fans who wish to play the best HiFi sound without compromising 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 an SR35-controlled network audio system to deliver the best sound quality. Additionally, it supports the full decoder of MQA 8X (Master Quality Authenticated) so that SR35 can play and stream HiFi MQA sound natively, true to the concept of A&norma that plays original sounds anywhere and at any time. With the SR35, you can choose from four DAC filters to create your sound signature. Design your sound with four different DAC filters and immerse yourself in pure sonic tranquillity!

RE-ENGINEERED UI/UX DESIGN FOR A THOROUGHLY TRANSFORMATIVE USER EXPERIENCE
The Astell&Kern A&norma SR35 comes with a redesigned Crimson-themed UI/UX transforming into an innovative true music player. The new UI/UX is designed so that you can quickly browse music categories and re-discover songs within your music library. Astell&Kern has also added an easy album art search function allowing you to re-discover the joy of viewing and interacting with music album art whilst listening to your favourite tracks. The crimson theme focuses on edge, simplicity, and dark mode keywords. The colour theme of black with red highlights lowers visual fatigue offering an intuitive user experience. The SR35 has also seen some much-needed improvements to its user-friendliness of app service, artist view, album sorting, and the album art search function.



ICONIC FUTURISTIC DESIGN WITH ANGULAR 3.6-INCH DISPLAY
The Astell&Kern A&norma SR35 is the prime example of the ultimate portability of the A&norma series. The compact size of the SR35 fits easily in your pocket. And weighing in at only 184g is light enough to carry without hassle or inconvenience. On the SR35, the tremendous dynamics of the A&norma series are represented by a great warrior's sword and shield. The volume control is also exquisitely crafted. The concave surface and single bold line on the side resemble a sword of combat and a shield, respectively. These symbolic shapes represent a warrior’s powerful force and characteristics. An "A" pattern on the rear glass of the SR35 indicates the first use of Quad DAC architecture in the A&norma series. Astell&Kern maintained their recognisable, angular display that fits nicely in the palm and further defines the heritage of the A&norma series.

What DAC chips are incorporated in the Astell&Kern A&norma SR35?
The Astell&Kern A&norma SR35 deploys the CS43198 DAC from Cirrus Logic in Quad DAC configuration.
What are the sampling/decoding rates supported?
The Astell&Kern A&norma SR35 supports Native DSD256 and PCM playback of up to 32 bit/384 kHz allowing you to enjoy HiFi sound without restriction and free from distortion.
Does it support MQA?
Yep! It does support 8X MQA.
What is MQA and how does it make a difference or how is it different from regular PCM & DSD files?
Our ability to hear well allows us to pinpoint the source of sounds. Our brains create a 3D acoustic image as sounds arrive at us, spaced out by milliseconds. This same capacity enables us to place the various instruments according to their sounds during a live performance. It's also the reason why listening to live music seems so intense and emotional, in contrast to recorded music, which frequently feels flat. The first solution to do so is MQA, which will take you back to the original performance by capturing this important timing information.
How does MQA work?
Transients over time are muddled when an analogue sound is translated into a digital signal, a process known as temporal blurring. As a result, recorded music sounds flat when compared to 'live' music since our ears are unable to distinguish the sources of individual sounds. This distortion can be removed with MQA to produce the most accurate 3D soundstage ever heard.
Does it offer Gain settings?
Yep! The Astell&Kern A&norma SR35 supports a 2-step Gain Level mode. The two-step gain setting with 'Normal' and 'High Gain' modes can generate a high current to create a powerful sound and excellent driver control.
What is the Bluetooth version and codec support that it provides?
The Astell&Kern A&norma SR35 is equipped with Bluetooth v5.0 with support for Bluetooth codecs like LDAC and Qualcomm® aptX™ HD.

Can streaming apps be downloaded?
Yep! You can have access to streaming apps like Tidal, Spotify, AmazonMusic, Moov, Qobuz, Deezer, FLO and many more.
Is it Roon Ready?
Yep!
What are the various DAC filters and how do they affect sound quality?
Below are the four DAC filters that you can choose from:
Low Latency Fast: Post echo enhances bass sound
Low Latency Slow: Minimal echo reproduces original sound
Phase Compensated Fast: Pre and post echoes make powerful sound
Phase Compensated Slow: Minimal echo reproduces original sound

RE-ENGINEERED UI/UX DESIGN FOR A THOROUGHLY TRANSFORMATIVE USER EXPERIENCE
The Astell&Kern A&norma SR35 comes with a redesigned Crimson-themed UI/UX transforming into an innovative true music player. The new UI/UX is designed so that you can quickly browse music categories and re-discover songs within your music library. Astell&Kern has also added an easy album art search function allowing you to re-discover the joy of viewing and interacting with music album art whilst listening to your favourite tracks. The crimson theme focuses on edge, simplicity, and dark mode keywords. The colour theme of black with red highlights lowers visual fatigue offering an intuitive user experience. The SR35 has also seen some much-needed improvements to its user-friendliness of app service, artist view, album sorting, and the album art search function.



ICONIC FUTURISTIC DESIGN WITH ANGULAR 3.6-INCH DISPLAY
The Astell&Kern A&norma SR35 is the prime example of the ultimate portability of the A&norma series. The compact size of the SR35 fits easily in your pocket. And weighing in at only 184g is light enough to carry without hassle or inconvenience. On the SR35, the tremendous dynamics of the A&norma series are represented by a great warrior's sword and shield. The volume control is also exquisitely crafted. The concave surface and single bold line on the side resemble a sword of combat and a shield, respectively. These symbolic shapes represent a warrior’s powerful force and characteristics. An "A" pattern on the rear glass of the SR35 indicates the first use of Quad DAC architecture in the A&norma series. Astell&Kern maintained their recognisable, angular display that fits nicely in the palm and further defines the heritage of the A&norma series.

The Astell&Kern A&norma SR35 supports Native DSD256 and PCM playback of up to 32 bit/384 kHz allowing you to enjoy HiFi sound without restriction and free from distortion.
Does it support MQA?
Yep! It does support 8X MQA.
What is MQA and how does it make a difference or how is it different from regular PCM & DSD files?
Our ability to hear well allows us to pinpoint the source of sounds. Our brains create a 3D acoustic image as sounds arrive at us, spaced out by milliseconds. This same capacity enables us to place the various instruments according to their sounds during a live performance. It's also the reason why listening to live music seems so intense and emotional, in contrast to recorded music, which frequently feels flat. The first solution to do so is MQA, which will take you back to the original performance by capturing this important timing information.
How does MQA work?
Transients over time are muddled when an analogue sound is translated into a digital signal, a process known as temporal blurring. As a result, recorded music sounds flat when compared to 'live' music since our ears are unable to distinguish the sources of individual sounds. This distortion can be removed with MQA to produce the most accurate 3D soundstage ever heard.
Does it offer Gain settings?
Yep! The Astell&Kern A&norma SR35 supports a 2-step Gain Level mode. The two-step gain setting with 'Normal' and 'High Gain' modes can generate a high current to create a powerful sound and excellent driver control.

Yep! You can have access to streaming apps like Tidal, Spotify, AmazonMusic, Moov, Qobuz, Deezer, FLO and many more.
Is it Roon Ready?
Yep!
What are the various DAC filters and how do they affect sound quality?
Below are the four DAC filters that you can choose from:
Low Latency Fast: Post echo enhances bass sound
Low Latency Slow: Minimal echo reproduces original sound
Phase Compensated Fast: Pre and post echoes make powerful sound
Phase Compensated Slow: Minimal echo reproduces original sound
