Review: Great product - Seller was very supportive and honest. - Hello All Buyers, I have received FiiO K11 instead of K11R2R, but the seller was addressed this issue quickly, I'm satisfied with their support and honesty. Besides, I have been using this unit last one week, well made DAC with easy to setup. In addition, I feel the DAC is perfect for decent for music listening, Bass I feel bit stronger than regular DAC, in comparison of Eversolo A-6, or Fiio K11.

Detali nie brakuje są za to znacznie bardziej naturalne niż w sztucznie oversamplowanych Sigmach. Faktycznie konkurować może jedynie 2x droższy Chord. Działa bez problemów w parze z wiimem ultra - przy zdecydowanie wyższej jakości dźwięku niż z wewnętrznego dac ess wiima. Oraz wyższej niż analogiczne Toppingi akm. Piękne metalowe wykonanie z podświetlanym logo. W pomiarze oscyloskopowym wyraźnie widoczne działanie full NOS (także dla Dsd), bez wprowadzanych artefaktów filtrów układów Delta Sigma. ## Frequently Bought Together - FiiO K11 R2R DAC and Headphone Amplifier for Home Audio or PC, 6.35mm and Balanced 4.4mm, RCA, Coaxial, Optical, 1300mW, 384kHz/24Bit DSD256 (Silver) - HIFIMAN Edition XS Full-Size Over-Ear Open-Back Planar Magnetic Hi-Fi Headphones with Stealth Magnets Design, Adjustable Headband, Detachable Cable for Audiophiles, Home, Studio-Black - Qudelix-5K Bluetooth USB DAC AMP with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/645812989-fiio-k11-compact-desktop-r2r-architecture-dac-and-headphone-amplifier](https://www.desertcart.co.za/products/645812989-fiio-k11-compact-desktop-r2r-architecture-dac-and-headphone-amplifier) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-31*
