Guten Tag,
Ich verkaufe meinen FiiO K11 R2R Kopfhörerverstärker.
Dieser wurde nur sehr wenig genutzt und ist praktisch neuwertig, die OVP und das gesammte Zubehör ist ebenfalls dabei.
Meldet euch bei Fragen gerne bei mir.
Dies ist ein Privatverkauf. Der Verkauf erfolgt unter Ausschluss jeglicher Gewährleistung und Sachmängelhaftung.
The FiiO K11 R2R is a standout entry in the desktop R2R DAC/amp category, offering genuine resistor-ladder sound at a surprisingly accessible price point. At €140 EUR, this excellent-condition listing is ambitious, sitting clearly above the 75th percentile (€131 EUR) of recent used comparables, with a median of €117 EUR and a 25th percentile of €109 EUR. It’s not a bargain, but it’s not absurdly overpriced either—more a premium for the “excellent” condition and likely original-owner care.
What makes it worth considering is the K11 R2R’s rare balance of true R2R architecture, solid build, and versatile inputs (USB, coax, optical) plus Bluetooth, all in a compact 420 g chassis. It drives both low- and high-impedance headphones cleanly, with balanced 4.4 mm output delivering up to 1.3 W @32 Ω. If this listing includes the original box, power cable, and any documentation, the extra €23 EUR over the median feels justified for a clean, ready-to-use unit in a product that’s still relatively new and well-regarded.
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.
