NEW GENERATION AMP TECHNOLOGY

The new SR35 is the first in the A&norma series to be equipped with New Generation AMP technology from Astell&Kern. Featured in the latest high-end A&ultima and A&futura range, the in-house amplifier has been designed to effectively eliminate noise at a high-power output.

The new amplifier technology built into the SR35 also features a two-step gain mode. New gain settings generate a high current output to produce a powerful sound with excellent driver control when using of sensitive IEMs and hard-to-drive headphones.

NEW USER INTERFACE

The SR35 comes with a reimagined, crimson-themed, intuitive user interface featuring a new album artwork search function. A new AK File Drop function in the SR35 makes wireless transfers more convenient than ever. Using the tool, files can be freely transferred through a PC, smartphone, or FTP program located on the same network.

Equipped with Dual Band Wi-Fi (2.4/5GHz) to provide strengthened network performance, music in the highest possible quality can be enjoyed through a wide range of streaming and Roon Ready services. The Astell&Kern A&norma SR35 Player also brings your other devices up to its level. Music from an external device, such as a smartphone, can now be played back in high quality on the SR35 through a new BT Sink function.

ROON READY AND MQA SUPPORT

Further new functionality comes with Roon Ready status, plus full MQA 8x decoder support enabling the SR35 to natively play and stream HiFi MQA tracks.

ASTELL&KERN DESIGN

Embodying the design principles of the A&norma range, the SR35 is powerful yet portable in its stature. The bold line at the side of the device that widens at the bottom symbolises, A&K tells us, a warrior’s sword of battle, while the concave surface of the refined volume crown represents a shield. These shapes combine in the design of the SR35 to indicate “the strength and consistency of the audio performance”.

ASTELL&KERN AK ZERO2 EARPHONES

These second-generation IEMs combine different driver technologies and are crafted in Japan.

MICRO RECTANGULAR PLANAR DYNAMIC DRIVER

The AK ZERO2’s micro rectangular Planar Dynamic Driver has been specifically developed to deliver high frequencies, using advanced technology to optimise the planar design for in-ear use.

PIEZOELECTRIC TRANSDUCER

The final piece of the picture is a 10mm Dynamic Driver with Piezoelectric Transducer technology. In the AK ZERO2, this design takes on both super-tweeter and bass extension duties.

Each driver is placed optimally in an acoustic chamber that is created through refined 3D printing technology. This design eliminates any unnecessary movement and resonance of the drivers for stable performance.
