This is a seller’s market for high-end tube DAPs right now, but the US$979 asking price on this used Astell & Kern CA1000T is a strong deal, sitting well below the 25th percentile of US$836 from our database and far under the median of US$884. You’re paying roughly US$47 less than the lowest recent comparable and nearly US$1,320 under the original US retail of US$2,300, making this an exceptional entry point into A&ultima’s flagship transportable tube player.
The CA1000T is revered for its tube-driven warmth, massive 10,100 mAh battery delivering 11+ hours, and four headphone outputs including 4.4mm balanced, plus RCA and optical/coaxial inputs for desktop use. At US$979, this represents genuine upside for a clean, well-loved unit that combines DAP, DAC, and amp in one chassis. Unless the condition is questionable or accessories are missing, this is a clear buying opportunity for enthusiasts seeking top-tier tube sound without the new-unit price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
