The CS43198 DAC from Cirrus Logic in Quad DAC configuration
For the first time in the A&norma series, the SR35 features the CS43198 DAC from Cirrus Logic. This DAC has been highly praised for its exceptional spatial perception and high resolution. In addition to this, a new audio circuit design has been implemented, incorporating unique Astell & Kern technologies, as well as the DAC and patented TERATON ALPHA technology to enhance dynamics, spatial perception, resolution, and channel separation.
Furthermore, the latest advanced amplification circuit, previously only available in flagship products, is now integrated into the SR35, offering significantly improved and industry-leading signal-to-noise ratio of 130 dB. The SR35 supports native DSD256 and PCM playback up to 32-bit/384 kHz, allowing you to enjoy true Hi-Fi sound without any limitations or distortions.
2 DAC or 4 DAC operation selection
The ability to switch between 2/4 DAC operation modes allows users to adjust and improve power management efficiency, further increasing continuous playback time. This feature is a key highlight of the A&norma series.
New Generation Amplifier Block
SR35 is equipped with a next-generation amplifier technology that has been applied in the A&ultima lineup, so A&norma users can also enjoy the highest level of sound provided by the A&ultima range with this exclusive, proprietary technology.
The next-generation amplifier technology applied in the SR35 is a unique Astell&Kern amplifier design that effectively improves noise cancellation at high output power. Thanks to this new technology, the SR35 has the same amplifier circuitry as the latest A&ultima and A&futura products, transforming into an amplifier worthy of a premium-class audio system, ranging from the choice of operational amplifier to component placement. To ensure reliable operation with different impedance, the current delivery capacity at the output has been increased to maximize the performance with various devices using a single SR35.
2-step gain mode for ideal reproduction
To ensure trouble-free use of sensitive headphones, the device must provide the appropriate output signal that matches the specifications of the connected device. The SR35 supports a 2-step gain mode, which is perfect for a wide range of headphones and IEM devices, while maintaining optimal sound output. The dual-stage gain setting in "Normal Gain" and "High Gain" modes allows for generating a high output current, creating powerful sound and excellent driver control. With an output voltage of up to 6 Vrms from balanced outputs, it can drive a wide range of high-impedance headphones.
TERATON ALPHA - the essence of A&K audio technologies combined in the SR35
In order to develop a new audio player comparable to the premium series, the company has utilized not only the latest DACs, but also the innovative audio technology TERATON ALPHA - the ultimate sound solution from A&K, enhanced for the SR35.
This unique technology, developed by Astell&Kern after endless research, aims to maximize the fidelity of the reproduced sound to the original source by efficiently eliminating power noises, power control, gain stabilization, as well as a fully transformed output audio interface. TERATON ALPHA, combined with the newly implemented HEXA structure and independent dual sound circuitry, recreates the purest original sound.
High autonomy
In addition to the main value of the A&norma series, which focuses on providing unlimited Hi-Fi sound reproduction anywhere and at any time, the SR35 offers the best portability in the market of digital audio players with extended playback time and increased output power.
The compact size of the SR35 easily fits in your pocket, and weighing only 184g allows you to carry it with you without any inconvenience. With a maximum 20-hour continuous playback, you can enjoy music without recharging throughout the day.
The SR35 is the perfect companion that you can use during long flights, as well as throughout the day at work and on vacation, guaranteeing you Hi-Fi sound anywhere and at any time.
Immerse yourself in music with the new user interface
The SR35 has received a revamped user interface in raspberry-themed design, allowing users to fully immerse themselves in the music listening process. The new user interface is designed to enable users to quickly browse music categories and rediscover songs in their music library. The convenient album cover search feature allows users to view album covers while listening to their music.
The "Crimson" theme focuses on the keywords edge, simplicity, and dark mode. The color scheme with black and red highlights reduces visual fatigue and provides an intuitively understandable user interface. Additionally, numerous other enhancements have been made to improve the convenience of working with applications, browsing artists, sorting albums, and searching for album covers.
Roon Ready and MQA
Roon Ready is a service for Hi-Fi enthusiasts who want to play high-fidelity sound without compromise on various devices through network systems. Roon Ready, available in some premium audio products, is now bundled with the A&norma series for the first time, offering you a network audio system with SR35 control to deliver the best sound quality. The SR35 supports full MQA 8X decoding, so it can stream Hi-Fi MQA sound, aligning with the A&norma concept of reproducing original sounds anywhere and anytime.
Wireless Hi-Fi sound through BT receiver
The BT Sink function connects the SR35 to an external device via Bluetooth, similar to connecting a smartphone to a Bluetooth speaker. Now you can play music from an external device, such as a smartphone, in high quality on the SR35 using the BT Sync function.
