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.
Review: Jedyny dac r2r dostępny w rozsądnej cenie, jakość zdecydowanie przewyższa o klasy wszelkie rozwiązania delta sigma w podobnych i wyższych cenach. 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.
