At £75, this Astell & Kern AK HC4 is a strong bargain, sitting well below the 25th percentile of £126 and nearly 66% under the median of £332 for used listings. The asking price is also roughly 66% lower than its original retail price of £219, making it an exceptional value for a functioning unit.
The HC4 is a well-regarded portable DAC/amp that delivers serious performance in a tiny form factor, supporting up to 32bit/384kHz PCM and DSD256 with impressively low THD+N (0.0005% unbalanced). It pairs the AKM AK4493S DAC with a custom amp to push 281 mW at 32Ω on its balanced 4.4mm output—enough power for many portable headphones. At this price, even with unknown condition, it’s a compelling buy for enthusiasts wanting high-res audio on the go without spending new money.

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.
