Astell & Kern SR25
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.
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.
