At £102, this is a much better proposition than settling for a basic entry-level dongle: it sits well below the £177 median for comparable used examples and comfortably below the £63–£347 middle-market spread’s lower quartile threshold. That makes it a strong deal, assuming the listing is complete and functional rather than merely an attractive price.
The KA17 is unusually capable for its size, combining dual ES9069Q DACs, THX AAA 78+ amplification, a useful display and both 3.5mm and 4.4mm outputs. Its real party trick is Desktop Mode, which can deliver up to 650 mW per channel balanced when externally powered—enough authority for headphones that leave ordinary dongles struggling. “Box opened” is hardly a concern here; check that the USB leads, power input and balanced output work, but at £102 this looks like a buying opportunity.

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.
