A&norma SR25 // Portable High-Resolution Audio Player
The A&norma SR25 is the latest answer to the never-ending question of "How do we get closer to the original sound the artist intended?" The SR25 supports native DSD256 and 32bit/384kHz audio for the first time in an Astell&Kern standard product and 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. It uses the new Performance Mode to adjust and optimize the system in order to produce near perfect sound quality when playing back high resolution audio.
With the SR25, the Astell&Kern team developed a completely different PCB design 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. The newly designed audio patterns and power circuits for distortion-free signal transmission and noise rejection are applied to each channel.
The aluminum body on the SR25 provides maximum sound quality, while suppressing noise as much as possible. In order to produce this unique style Astell&Kern is famous for, 5-axis machining is performed instead of traditional 3-axis machining used in general machining. The use of laser ground extension technology gives you the best sound possible, without interference or distortion.
Astell&Kern's vibration-free processing machines are the same ones used by expensive Swiss luxury watch manufacturers. This is reflected in the crafting of the volume wheel which is processed precisely like the crown of a luxury watch for the best operating feel.
The SR25 firmware is based on Android 9.0, which adds a number of behind the scene features and upgrades to provide more stable operation over previous versions of Android OS. The use of Android 9.0 ensures the most popular music streaming apps installed via Open APP will be fully compatible with your Astell&Kern player now and with future app updates.
