FiiO, modèle K13 R2R Silver, ampli casque et DAC, égaliseur 10 bandes.
The asking price of US$347 is significantly ambitious for this used FiiO item, sitting well above the 75th percentile of US$180 from your database and far exceeding the median of US$105. While the retail price hovers around US$320, paying US$347 for a used unit means you are paying more than new, which is not a fair deal or a bargain by any market standard.
This FiiO K13 R2R is a well-regarded desktop DAC featuring a true resistor-ladder architecture, powerful 2400mW balanced output, and versatile modes including preamp and NOS/OS switching. It delivers natural sound quality and strong build quality rated 9/10, making it a worthy upgrade for IEMs and demanding headphones. However, at this inflated price, the lack of verified original-owner condition or included accessories makes it a poor buying opportunity compared to waiting for a listing near the US$105 median.
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.
