A&norma sets the standard of Hi-Fi audio for novice listeners. The SR15, the first model of A&norma, is the beginning point of the Hi-Fi Audio experience that allows you to enjoy the philosophy and technologies of Astell&Kern, which is accoladed by audiophiles around the world.
- Dual DAC of CS43198, MasterHIFI™ tier chipsets from Cirrus Logic
- Enhanced audio processing power and snappy UI with Quad-core CPU
- Native DSD playback and playback-focused User Interface
- Powerful audio performance curated by Astell&Kern's know-how
The A&norma SR15 uses two audio DAC chips for a Dual-DAC setup. These chips are known for their use in Home Hi-Fi systems which offer greater presence compared to the inferior DAC chips designed for mobile devices.
There are many devices that use DAC chips for audio processing, however there are different tiers and quality of chips sought by Hi-Fi audio manufacturers to deliver an experience close to the original performance.
A&norma SR15 has adopted the MasterHIFI™ class DAC, CS43198 for the first time in a portable system. At Astell&Kern, we believe that true Hi-Fi should sound as close as possible to the original performance. The CS43198 is one of few DAC chipsets that is capable of bringing us even closer to the original when it's matched with the analog amp design of Astell&Kern. In result, it brings even more liveliness and warmth of sound without distortion.
Furthermore, A&norma SR15 supports native DSD bit-to-bit, and gets one step closer to the Hi-Fi system.

Specializing in low power ICs for audio and voice signal processing applications, Cirrus Logic's products span the entire audio signal chain, from capture to playback, providing innovative products for the world's top smartphones, tablets, digital headsets, wearables and emerging smart home applications. Now they have introduced the MasterHIFI™ chipset solutions for excellent audio reproduction performance.
MasterHiFI™ class designation is only given to their chipsets that meet their highest audio performance standard. It will deliver your music as the musicians and producers wanted you to hear it.
Enhanced Audio Processing Power with Quad-core CPU
Some may think that only sound matters in Hi-Fi systems. While it does matter greatly, there are other factors that influence your immersive music experience as well. A&norma is designed to remove any distracting elements, including noise, distortion and unintuitive user interface.
The Quad-core CPU gives you even more processing power for your digital music and a lot faster, natural UI experience. Get lost in your music without distractions.
- 24-bit, 192 kHz Bit-to-Bit Playback
- The A&norma SR15 plays any resolution of digital files up to 24-bit/192 kHz, bit-for-bit.
- For 32-bit audio, downsampling is performed by the SRC (Sample Rate Converter) method.
- DSD is native up to 64 MHz and DSD 128 MHz is converted to PCM for playback.
New Intuitive User Interface
A&norma SR15 has adopted the user interface of the A&ultima SP1000, which has grown famous for its intuitiveness and simplicity.
- Player is in the main. All functions are centered on "music replay."
- Secure access to the music DB and features to manage music files
- Minimum menu depth and simple structure
