The A&norma series was created to enjoy Astell&Kern's premium sounds 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
The SR35 inherits these strengths while applying the amplification and audio design that was applied to Astell&Kern's premium products to deliver the authentic sound quality that Astell&Kern is so known for.
The ultra-compact SR35 offers 20 hours of continuous playback, while supporting quad DACs and two-step gain control, and the first introduction to the A&norma line of next-generation amplifier technology using Astell&Kern's long-standing know-how for even more delicate and clear Hi-Fi sound at higher output.
In addition, a new audio circuit design has been implemented that incorporates exclusive Astell&Kern technologies together with the quad DAC and our patented TERATON ALPHA technology to achieve an extraordinary advance in dynamics, sense of space, resolution and level of separation. Additionally, our latest technologically advanced amplification circuitry, which was only available in our flagship products, has now been incorporated into the SR35, with a dramatically improved and industry-leading 130 dB SRN.
A Dual / Quad DAC switching mode is offered that allows users to fine-tune and improve power management efficiency, further enhancing the long continuous playback time, a key feature of the A&norma series.
The SR35 supports native DSD256 and PCM playback up to 32bit/384kHz, allowing you to enjoy unrestricted, distortion-free authentic Hi-Fi sound.
The essence of Astell&Kern technology - Equipped with new generation AMP
The Astell&Kern brand philosophy - refusing to overlook even the smallest differences in sound quality - has been recognized by numerous media outlets and audiophiles through our multiple releases of premium audio players that combine innovative circuits and amplification technologies.
The Next Generation AMP technology applied to the SR35 is an exclusive Astell&Kern amplifier design that effectively improves noise reduction at high powers. 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. .
Additionally, in order to reliably operate output sources of different impedances, the current handling capacity at the output end has been increased to maximize the performance of multiple devices with one SR35.
The SR35 supports a 2-step gain level mode to create the perfect match for a wide range of headphones and IEMs, while maintaining optimal sound output. 2-step gain adjustment with "Normal Gain" and "High Gain" modes can generate high current output to create powerful sound and excellent control of transducers. With up to 6 Vrms on balanced connections, driving high impedance headphones has never been easier.
The SR35's new AK File Drop feature makes file transfers easier and more convenient. With AK File Drop, you can freely transfer files wirelessly via a PC, smartphone or FTP program located on the same network. Music file management is now possible with a wireless and cable-free solution.
Roon Ready, available on some high-end audio products, now arrives for the first time with the A&norma series, giving you a networked audio system controlled by SR35 to deliver the best sound quality.
In addition, it supports the full 8X MQA decoder so that the SR35 can play and transmit MQA Hi-Fi sound natively, true to the A&norma concept that reproduces original sounds anywhere, anytime.
SR35 offers dual-band Wi-Fi (2.4/5GHz), providing improved network performance for enjoying Hi-Fi music through various streaming and Roon Ready services.
ReplayGain adjusts the playback volume automatically and smoothly.
ReplayGain has been applied, which adjusts sound sources with different volumes to an identical level. Now, enjoy your own playlists seamlessly thanks to the SR35's ReplayGain feature.
The BT Sink function connects the SR35 to an external device via Bluetooth, similar to connecting a smartphone to a BT speaker. Music from an external device, such as a smartphone, can now be played in high quality on the SR35 using the BT Sink function.
The SR35 supports native DSD256 and up to 32bit/384kHz with Astell&Kern's excellent audio technology, allowing you to fully enjoy your favorite music.
