Presentation
The FiiO K11 Silver is a desktop DAC amplifier fitted with a passive R2R converter comprising 192 matched resistors, ensuring digital-to-analogue conversion of PCM streams up to 24-bit/384 kHz and DSD256.
The output power reaches 1300 mW in balanced mode, covering an impedance range of 16 to 350 ohms. Three gain levels allow the power to be adjusted according to the type of headphones used.
Available inputs include a USB-C port compatible with computers and mobile devices, an optical input and a coaxial input for CD players or televisions. The RCA output allows integration into an existing hi-fi system.
The headphone outputs include a 6.35 mm unbalanced jack and a 4.4 mm balanced jack, compatible with the majority of headphones and earphones on the market.
The FiiO K11 Silver is suitable for desk, living room and home studio set-ups requiring a compact DAC amplifier with versatile connectivity options.
