New, the FiiO K7 has typically sold around £190, so £130 used is a fair price rather than a bargain. It exactly matches the median of recent comparable listings, sitting comfortably between the £113 and £141 quartiles. With the condition unspecified, it isn’t obviously underpriced, but it remains sensible if complete and working properly.
The K7 is a particularly capable desktop DAC/headphone amplifier: its THX AAA 788+ amplification offers ample power for demanding headphones, while the balanced 4.4mm output, USB, optical, coaxial and RCA inputs make it a versatile system hub. The standard model is already excellent value; the K7 BT version adds useful Bluetooth flexibility. At this price, check that the power supply, remote if applicable, and original accessories are included, and test both headphone outputs for clean channel balance.

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.
