A&norma SR25 MKII Overview

A Pocket Powerhouse
True to the core values of Astell&Kern, high fidelity sound lies at the heart of the SR25 MKII, delivering exceptional audio performance to a diverse range of music lovers.

The SR25 MKII offers more versatile connectivity options with the addition of a 4.4mm balanced output for the first time in an A&norma player, LDAC, as well as Qualcomm® aptX™ HD, which support and deliver true audiophile sound quality.

Better Sound. Familiar Feel.
Not all DACs sound the same.

The SR25 MKII delivers improved performance across the board compared to the SR25, including bass response, dynamic range, soundstage, imaging and more.

The SR25 MKII utilizes Astell&Kern’s latest audio design technology for clear and natural high-resolution sound with more clearly defined upper and lower ranges providing listeners with a deeper, more rounded sound.

The SR25 MKII is capable of bit-to-bit playback for files up to 32bit/384kHz and Native DSD up to 11.2MHz, allowing for uncompressed sound quality, staying true to the artist’s original intention, in high-resolution and with minimal distortion.

With seamless playback performance supporting Native DSD256 up to 32bit/384kHz, you will derive even more pleasure from your music.

Multiple Output Options
The SR25 MKII supports 4.4mm balanced output. With 2.5mm, 3.5mm and 4.4mm output options, you can connect an even wider variety of devices.

The 4.4mm balanced output provides improved dynamic range and bass response, supports a wide soundstage, offers clear imaging, and captures subtle details in the audio source.

A&norma SR25 MKII Features

Excellent Continuous Playback Time
No need to worry about battery life. The SR25 MKII can play continuously for 20 hours with just one full charge, thanks to its optimized, energy-efficient circuitry.

Enjoy your own personal musical performance anytime, anywhere with the SR25 MKII’s extended playback time and portability.

* Music in FLAC format, 16 bit, 44.1 kHz, unbalanced, volume at 50, EQ Off, LCD Off

Silver Plating Shield Can
Astell&Kern products apply shield cans so that noise and electromagnetic interference, which occur when the countless parts are in operation, do not affect the audio block.

Wireless Hi-Fi Sound Through BT Sink
The newly introduced BT Sink function connects the SR25 MKII 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 SR25 MKII using the BT Sink function.

AK File Drop to Enjoy Wireless Transfers
The new AK File Drop function in the SR25 MKII makes files transfers easier and more convenient.

Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network.

Music file management is now possible with a cableless, wireless solution.
