Offered is „SR25“ by Astell & Kern as second-hand device from the category „Digital Sources (CD/DVD/Streamer...)“ on audio-markt.de - the online market place for high-end. The advert with the number 6669396327 ends on 13.12.2026 at 09:31 o'clock.
This is a strong deal. At €349, it sits below the €366 25th-percentile comparable and well under the €383 median, making it a genuine bargain if the condition is accurately described. It is notably cheaper than the €400 upper-quartile asking price, without being so low that it automatically suggests a problem.
The SR25 remains a very capable compact player: its dual Cirrus Logic DACs, clean 3.5mm and 2.5mm balanced outputs, native high-resolution playback, USB-C, expandable storage, and LDAC/aptX HD support make it unusually versatile. Claimed battery life is around 21 hours, though actual runtime depends on use. At this price, check that the touchscreen, volume control, both headphone outputs, charging port, and battery all behave properly; otherwise, this is an easy recommendation.

Astell&Kern emerged from South Korea's rich audio heritage, launching its first product in 2012 and officially founding as a brand in 2013 in Seoul. Rooted in the legacy of iriver's MP3 players dating back to 1999, the company—now a subsidiary of Dreamus—embodies a philosophy drawn from its name: "Astell" (Latin for star) and "Kern" (German for core), symbolizing an unrelenting pursuit of music's original sound. This origin story reflects decades of accumulated expertise in premium audio craftsmanship.
The brand focuses on high-fidelity portable and home audio solutions, excelling in digital audio players (DAPs) like the iconic AK100 and A&ultima series, alongside headphones, in-ear monitors through collaborations, home audio systems, and accessories. Their designs prioritize advanced noise reduction, proprietary amplifier architectures, and support for hi-res audio files, delivering uncompromised playback without venturing into speakers, turntables, or cables.
Positioned firmly in the high-end audiophile market, Astell&Kern commands respect among discerning listeners for its "Difference in Sound Quality"—a sensory depth that captures the emotion and space of every note. Renowned for luxury builds and cutting-edge R&D, it leads the global premium DAP segment, appealing to buyers who demand superiority over mass-market compromises.
