Astell&Kern’s new SR25 entry-level portable player packs a punch

Editor’s Brief: One of the most coveted names in hi-fi audio players, Astell&Kern, unveils its new affordable portable high resolution audio player, A&norma SR25, which supercedes the previous much loved SR15. The SR25 embraces the adequately modern Android 9.0 that uses OpenApp for music apps installation. The SR25, despite being the entry-level Astell&Kern product, is certainly no slouch, and brings plenty of performance, sound quality, and a design of sheer class to the table. Read more below.

SINGAPORE — Global leader in high-resolution products Astell&Kern has unveiled the second player in its A&norma line of portable high-resolution audio players, the A&norma SR25. The SR25 is an upgrade of the award-winning A&norma SR15 player, and supports native playback of DSD256 and 32-bit/384KHz PCM high-resolution audio.

The SR25 features two Cirrus Logic 43198 MasterClass DACs in dual-mono configuration like the SR15, but adds a number of new features such as a faster Quad-core CPU and newly designed circuitry to improve sound quality enhancements.

The A&norma line of portable audio players from Astell&Kern are designed to be an industry standard to play back high-resolution audio in a stunning, high-end, luxurious design and reproduce sound as it was intended by the artist and engineer who originally recorded it, at an affordable price.

A first for Astell&Kern players, the SR25 adds LDAC Bluetooth support, allowing users to wirelessly stream 24-bit hi-res audio to compatible speakers, headphones or IEMs. The SR25 also provides 20+ hours of continuous music playback, more than twice the playback time of the SR15 and longer than any other Astell&Kern player.

The SR25’s unique design balances user convenience with aesthetic factors. It features an aluminium body with an ultra-precision volume wheel machined with a vibration-free process used for luxury watches. The aluminium body suppresses noise and improves sound quality, while the thin-bodied design allows the user to easily hold and operate the 3.6-inch touchscreen display with one hand.

“The SR25 is a new premium product that brings the philosophy of Astell&Kern to provide music the way it was meant to be heard, without compromise to an affordable, high quality player, with a luxury design that has received international award recognition,” said Baek Chang-Hum, Director of Dreamus, parent company of Astell&Kern.
