Performance Mode for Ultra High Resolution Sound

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.

Bit-to-Bit playback is available in models up to the SR25 MKII 32 bit 384 kHz. Native DSD audio is available up to 11.2 MHz, 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 32 bit/384 kHz, 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.

Enjoy your music without worrying about adaptors.

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.

The SR25 MKII has taken it a step further by applying highly conductive, hyper-pure silver plating on the existing shield cans for perfect shielding that provides excellent audio performance.

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 its portability.

* Music in FLAC format, 16 bit, 44.1 kHz, unbalanced, volume at 50, EQ Off, LCD Off
* Playback time may vary depending on the user environment.

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.

ReplayGain Automatically and Uniformly Adjusts Playback Volume

ReplayGain, which adjusts sound sources with different volumes to an identical level, has been applied. Now, enjoy your own playlists seamlessly through the ReplayGain feature on SR25 MKII.

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.
