Overview

One Step Closer to the Original Performance

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.

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.
