The SR15 is the first model of Astell&Kern's newly introduced standard line. 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 accolated by audiophiles around the world.
One Step Closer to the Original Performance 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.
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.
USB Audio A simple USB connection will allow the A&norma SR15 to be used as a digital music storage device and /or pre-amp to output digital audio through USB. The A&norma SR15 transfers DSD in native format through DoP (DSD over PCM) and converts DSD to PCM for output for external USB Audio that do not support DoP.
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.

Master Quality Authenticated MQA 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 SR15 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The SR15 Now Playing status shows green or blue light to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.
