Product Information

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?"

Features

  • Quad-Core CPU
  • Cirrus Logic CS43198 Dual DAC
  • 32bit/384kHz Bit-to-bit Playback
  • 3.6" 720x1280 Touch Display
  • Aluminum Body
  • 21 Hours Continuous Playback

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 to 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 and efficiency are not properly taken into consideration, the input/output voltage difference becomes large, and 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. In addition, poor power efficiency will result in shorter playback time. The SR25 set a big challenge for the Astell&Kern engineering team – add the longest playback time of any previous Astell&Kern product, while maintaining the signature Astell&Kern 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 playtime, 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.

No Compromise on Sound, Even When Connected Wirelessly

In addition to 24-bit music playback via aptX HD Bluetooth as in previous Astell&Kern players, the SR25 adds LDAC support to give users more options to listen to high-resolution audio wirelessly. Now you can enjoy Astell&Kern's high-quality sound when paired to Bluetooth earphones, headphones and speakers.

Astell&Kern's Exclusive Metalworking Technology

Astell&Kern products are often compared to art sculptures, with colorful faces and angles not found in other products. This precise design work is based on Astell&Kern's long accumulated know-how and highly precise metalworking technology. 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. All metal must be processed at once without interruption. In addition to 5-axis machining, Astell&Kern has perfected it's crafting of metal through thousands of hours of trial and error. Only after mastering these techniques that Astell&Kern has developed, can the beauty of the metal shine through. The vibration-free processing machines used by Astell&Kern 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.  Astell&Kern products are designed to achieve perfect integration at whatever angle you look at it in your hands. The Aluminum body on the SR25 provides maximum sound quality, while suppressing noise as much as possible. The use of laser ground extension technology gives you the best sound possible, without interference or distortion. Astell&Kern combines these small parts to make a big difference in the quality of our products that no other manufacturer can match.

Latest System Optimization for a Better User Experience

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. Astell&Kern customizes Android to provide a fully optimized system and user interface, designed to give users a smooth, fluid musical playback experience.

MQA

MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Visit mqa.co.uk for more information. Astell&Kern SR25 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.
