£58 is a solid buy on this one: it sits below the £79 median and comfortably under the £137 75th percentile, so this is priced in bargain territory rather than merely fair. For a boxed unit with cables, that makes the deal stronger still, especially since the KA3 is generally well liked for its clean, punchy sound, low noise, and handy 3.5mm plus balanced 4.4mm outputs.
What makes it worthwhile is simple: it’s a compact, capable dongle DAC/amp that gives good power for IEMs and many headphones, with the extra flexibility of balanced output if your chain can use it. If the box and accessories are complete and it’s working properly, this looks like an easy recommendation at the asking price.

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.
