Hi-Fi Standards Redefined, AK SR25 – a development of the brilliant SR15, with improved features including extended battery life. The essence of Astell&Kern’s philosophy that sound quality is never compromised is exemplified in the SR25, which expresses every musical detail and bit-perfect playback as only Astell&Kern can.

A&norma SR25

The SR25 is the second model in the Astell&Kern A&norma standard line.

Beginning with the AK70, Astell&Kern’s goal was to bring high resolution audio and the Astell&Kern sound to more music lovers.

This goal continued with the successor to the AK70, the A&norma SR15, and now evolves further as the SR25, a premium product that fully embraces Astell&Kern’s philosophy and technology, now available to the masses.

The SR25 is the latest answer to our never-ending question of “How do we get closer to the original sound the artist intended?”
The SR25 improves on the SR15 by:

Adding a new, faster Quad-Core CPU paired with the Dual Cirrus Logic CS43198 Master Hi-Fi level DAC, first used on the SR15

  • Native playback support for DSD256
  • A new class-leading performance mode for ultra-high quality playback without compromise
  • Newly designed circuitry to improve sound quality enhancements
  • Addition of Bluetooth LDAC codec to give users more options for higher quality wireless sound

The essence of Astell&Kern’s philosophy that sound quality is never compromised is exemplified in the SR25, which expresses every musical detail and bit-perfect playback as only Astell&Kern can.

Perfect Circuit Design for the Highest Sound Quality

Proper playback of DSD256 and 32bit/384kHz digital audio requires a high-performance CPU and fast memory speed, along with an audio path suitable for high-speed signal processing.

Optimizing the length of the audio path is a very important part, as failing to properly do so can create a time delay between the signals resulting in sound abnormalities.

With the SR25, the Astell&Kern team developed a completely different PCB design from the existing SR15 to process the high speed signals where required, resulting in audio path lengths that are the same, allowing for super-high resolution sound without any delay.
Furthermore, newly designed audio patterns and power circuits for distortion-free signal transmission and noise rejection are applied to each channel.

The result is an Ultra Low Noise Filter that allows you experience Astell&Kern’s flawless sound, with Zero Noise, on the SR25.
