Astell&Kern is the ultimate Hi-Fi audio system
Astell&Kern is the ultimate digital music source that brings you Mastering Quality Sound or MQS. Astell means ‘Stars’ in Latin and Kern means ‘Center’ in German. We believe Astell&Kern is the center of music.
Original music performances recently have been captured in digital almost exactly as they were performed due to new and advanced recording technologies currently available. These great-sounding recordings are mainly listened to in inferior sound formats, such as MP3 or streaming services. With the debut of the MP3 format, music lovers scarified the quality of the sound for the convenience of being able to carry their music collection wherever they went. Because MP3 heavily compresses the original file for the sake of convenience, you only hear inferior vocals and instruments, and the full soundstage and ambience from the original recordings is missing. The movement of the original performance often disappears when listening to compressed MP3 music. After agonizing over these issues, Astell&Kern was our solution to the poor quality of musical sound for the sake of portability, and our way to ultimately bring back the original sound quality of the music, MQS, back to music artists, recording engineers and professionals.
Astell&Kern pursuit is to provide the natural and original sound without distortion. It offers almost the exact presence with tiny details you wouldn’t have noticed from other music systems by playing back high-resolution music bit for bit, exactly as it was recorded. The exact sound without missing any bit of the live performance in recordings is what Astell&Kern is known for.
The power of true sound from Astell&Kern has been experienced and also from famous audio exhibitions around the world. Astell&Kern is now admired by music lovers from many countries, including USA, China, Japan, UK, France, and many more around the world.
The New Hi-Fi Standard
Introducing the SR25, the second model in the A&norma standard line. 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 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.

Performance Mode for Ultra High Resolution Sound
The SR25 supports native DSD256 & 32bit/384kHz audio for the first time in an A&K standard product & boasts performance that cannot be compared with other competitors' products.
The SR25, which is smaller than other players, has been developed to achieve stable, ultra-high resolution sound. We have developed a new Performance Mode with the SR25 that automatically optimizes & sets the memory mode in the system according to the data size of the source being played.
As the resolution of the sound source increases, it is necessary to process a large amount of data rapidly. If this part is not optimized, sound breakup may occur. To prevent this, the SR25 uses the new Performance Mode to adjust & optimize the system in order to produce near perfect sound quality when playing back high-res audio.
Experience ultra-high resolution with the SR25's Performance Mode, which reproduces even the smallest, minute details of the original recording the artist was looking for, without compromise.
Perfect Circuit Design for the Highest Sound Quality
Proper playback of DSD256 & 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.
Embark on a Musical Journey That Lasts the Entire Day
If the power supply's stable design & efficiency are not properly taken into consideration, the input/output voltage difference becomes large, & when the output current is large, the output voltage can become unstable. This leads to excessive noise being generated, which can be a major cause of poor sound quality. Also, poor power efficiency will result in a shorter playback time.
The SR25 set a big challenge for the A&K engineering team – add the longest playback time of any previous A&K product, while maintaining the signature A&K quality sound, and a low-noise floor.
In the SR25, the team not only applied highly efficient components, but they focused on developing circuit optimizations to get the most out of their performance. The result is up to 21 hours of continuous play time, more than double the previous generation SR15, with no compromise in sound quality.
No need to worry about battery life while on your daily journey, just have fun on your Music Trip with the SR25.
