Unknown condition, so the asking price needs a little context—but at GBP £132 it is a fair buy, sitting just above the GBP £130 median and comfortably within the typical GBP £113–£141 range. It is neither a bargain nor overpriced; a clean, fully working example with its original power supply would justify the money.
The K7 remains a particularly capable desktop DAC/headphone amp: its dual THX AAA 788+ amplification gives it ample drive, while the 4.4mm balanced and 6.35mm outputs, USB/optical/coaxial inputs, and RCA line output make it unusually versatile at this level. Before buying, confirm the volume control is smooth, both headphone outputs work, and the power supply is included. If condition proves good, GBP £132 is a sensible enthusiast purchase rather than a price to haggle hard over.

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.
