Recent comparable sales put this model at a £278 median, with the lower quartile at £59 and upper quartile at £375. At £115, it sits comfortably below the median and is close enough to the lower quartile to count as a strong deal, assuming the unit is working and complete.
The K7 remains a particularly capable desktop DAC/amp: dual AK4493SEQ DACs, THX AAA 788+ amplification, USB/optical/coaxial/RCA inputs, and both 6.35mm single-ended and 4.4mm balanced headphone outputs. It has ample power for demanding headphones, useful gain and output-mode switching, and enough connectivity to serve as a compact hub in a desktop system. With the condition listed as unknown, check that the volume control, input selector, outputs, power supply, and included USB cable are present—but at £115, a tested example would be an easy recommendation.

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.
