De la marque FiiO, modèle K7, ampli casque et DAC USB, module d'amplification THX AAA 788+.
Compared with a new desktop DAC/amp at around US$200, this sits in the sweet spot for a serious used buy: at US$222 it’s well below the recent used median of US$414 and even under the 25th percentile of US$368, so it reads as a strong bargain rather than a stretch. For a current model with balanced output and lots of power, that’s excellent value.
The appeal is straightforward: the K7 is a respected do-everything desktop DAC/amp with dual THX AAA 788+ amplification, balanced 4.4mm out, and enough drive for most headphones in the 16–300Ω range. It’s especially attractive if you want clean, punchy performance without paying for extras you may not need. At this price, a complete, working unit is the kind of pickup enthusiasts should move on quickly.

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.
