Product Description

Designed to reproduce audio as the creator's intended, the A&norma SR25 Portable High-Resolution Music Player from Astell&Kern delivers high-fidelity acoustics you can take with you. Wrapped inside a stylish aluminum body is a host of technological advances in audio engineering. You get a quad-core CPU that's paired with dual Cirrus Logic CS43198 DACs that support 32-bit/384 kHz bit-to-bit playback and native DSD256. With up to 21 hours of playback, you can enjoy rich and dynamic sound all day long.

This kind of audio quality is provided regardless of how you listen, so with the SR25 you don't have to compromise when using wireless headphones or speakers. Aside from 3.5mm unbalanced and 2.5mm balanced headphone outputs, it supports 24-bit playback via aptX HD Bluetooth, as well as support for LDAC. All of this technology is at your fingertips and can be controlled via the 3.6" 720p TFT LCD and convenient external analog controls. For a smooth, user-friendly experience, Astell&Kern runs the SR25 on a customized Android 9.0 operating system.
