Fiio, modèle K9 AKM, ampli casque et DAC, Compatible 32 bits / 768 kHz et DSD.
US$526 is well above the typical used market here: it clears the 75th percentile of US$199 by a wide margin, so this reads as ambitious rather than fair. Against a median of US$110 and a 25th percentile of US$65, the listing is pricing like a premium or near-new unit, not a normal used buy.
That said, this is a respected desktop DAC/amp stack with a strong reputation for clean power, flexible inputs, and enough drive for most headphones, so the right buyer may still pay up if the unit is genuinely pristine, boxed, and complete. The upside is mainly convenience and condition; at this level, I’d want original accessories, proof it works flawlessly, and some justification for the premium before calling it a good buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
