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.

The new design of A&norma SR25 incorporates drastic changes without losing the balance between an optimal user experience, looks and keeping the A&norma design identity. The harmonious combination of these various design aspects symbolize the rhythmic feel and freedom of music. The player features layers of various sized rectangular surfaces with added angles to invoke the sense of pulsating musical rhythm from its design. Precisely milled cuts resemble various reflections of light and create a depth of space around the volume wheel that further emphasizes the bold light reflections that are created at different angles of view on the entire player.

On the back, the bold oblique cut surface of the rear glass meets the triangular shapes that surround the volume wheel. The patterns of the rear glass beautifully express the spreading of light when it is reflected off the surface. The rhythmic pattern on the rear glass will change as light is reflected at different angles.
The new SR25 is ideal for one-handed operation and is a perfect fit no matter which hand you choose to hold it in. The angle of the front screen and extra space around it gives you the perfect grip when it's held.
