In the quest to get closer to the sound which the artist intended, Astell&Kern has developed the latest SR25 which is an upgrade to their previous model SR15. The latest SR25 features a Quad-core CPU along with the debutant Dual Cirrus Logic CS43198 Master Hi-Fi level DAC. It also extends native playback support for DSD256.
The SR25 debuts with the native DSD256 and 32bit/384kHz audio which has never been used in a standard Astell&Kern player before, allowing it to deliver unrivalled performance. It has a new performance mode that optimizes the performance depending on the data size of the source being played. This results in the production of ultra-high-resolution audio without any break-up.
The SR25 employs Astell&Kern's uniquely developed PCB design which helps in better processing the high-speed signals and delivering lag-free high-res sound without reducing the audion path lengths. To add more efficiency, the new circuit design and audio patterns implement distortion-free signal transmission and noise reduction to each channel. Furthermore, the laser ground extension tech delivers the best sound without any distortion. All thanks to the ultra-low noise filter that helps deliver a noise-free flawless sound.
The design of the SR25 is the result of Astell&Kern's Precise Metalworking Technology. The aluminum body is designed to deliver high-grade sound quality by suppressing noise. It features rectangular surfaces with added angles. The perfect cuts are similar to the reflections of light and it makes space depths around volume wheel which further highlights the reflections. It's built to be efficiently used with one hand. Additionally, the front screen angle adds more space around it to provide a better in-hand grip.
The SR25 delivers almost 21 hours of playtime which is two times the battery life of its predecessor. It supports aptX HD Bluetooth codec for 24-bit music playback along with the advanced LDAC codec for transferring high-resolution audio wirelessly. So pair the SR25 with Bluetooth headphones and speakers and be rest assured of the audio quality.
The firmware of the SR25 is based on the Android 9.0 OS, opening your door to music streaming applications. Astell&Kern further optimizes the OS for a fluid and efficient music listening experience. Stream your favourite songs over .apk apps like Tidal, Spotify, Amazon Music, Apple Music and more with the Open APP Service. The MQA (Master Quality Authenticated) allows you to play MQA audio files and while offering a sound that matched to the original master recording.
