At £847, this is an ambitious asking price rather than a used-market bargain: it sits well above the £347 75th-percentile figure and nearly five times the £177 median from six recent sales. “Box opened” may mean effectively unused, but the seller needs to justify a substantial premium with a full warranty and complete accessories.
The K19 is a genuinely capable flagship desktop unit, combining a powerful THX AAA 788+ amplifier with extensive USB, HDMI/ARC, optical, coaxial and Bluetooth connectivity. Its balanced outputs, preamp functionality and sophisticated EQ make it unusually versatile, while the available power suits demanding headphones as well as sensitive IEMs. At this money, though, it should be pristine, fully tested and properly documented; otherwise, waiting for a materially lower price would make more sense.

Fiio, founded in 2007 in Guangzhou, China, emerged as a specialist in portable audio gear, initially crafting components like speakers for brands such as Meizu before launching its own lineup. The name blends "Fi" from hi-fi fidelity with "iO" symbolizing digital one's and zeros, evoking authentic sound and modern convenience, while its Chinese rendering "飞傲" conveys innovative vitality. From modest beginnings, the company expanded into a 15,000-square-meter industrial complex by 2022, solidifying its role as a prolific developer of music-centric electronics.
The brand excels across a broad spectrum of portable and desktop audio categories, with flagship strengths in high-resolution digital audio players (DAPs), USB DACs, portable headphone amplifiers, and in-ear monitors. Its portfolio also encompasses cables, desktop amps, and select speakers, prioritizing versatile, high-performance solutions for on-the-go and home listening without venturing into turntables or large-scale hi-fi systems.
Fiio occupies a commanding mid-tier position in the global audiophile market, renowned for delivering premium sound quality at accessible prices that punch above their weight. Praised by enthusiasts for reliability and value, it appeals to discerning buyers seeking refined portable setups over luxury excess, backed by worldwide distribution and a track record of user-acclaimed innovations.
