The New Hi-Fi Standard, 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.
