The FiiO K11 is a DAC and headphone amplifier that delivers impressive power and sound quality. Featuring a Cirrus Logic CS43198 DAC chip and dual SGM 8262 amplifiers, it supports PCM up to 32-bit/384kHz and DSD up to DSD256. The K11 can drive demanding headphones without distortion and has a high signal-to-noise ratio, making it suitable for critical listening. It has multiple input options, including USB, coaxial, and optical, with outputs for 6.3mm SE, 4.4mm BAL, RCA, and coaxial. With an output power of 520mW at 32Ω on the 3.5mm SE output and 1400mW on the balanced 4.4mm output, it can effectively power a variety of headphones and IEMs. The K11 is designed with a high-resolution VA display, which provides clear information about input source, sample rate, volume level, and gain setting. Users have reported that the K11 maintains a neutral tonality and delivers excellent imaging and dynamic range, especially when paired with high-impedance headphones like the Sennheiser HD 580 and Modhouse Argon MK3. While it lacks additional features like Bluetooth connectivity, its performance and build quality make it a substantial choice for desktop audio setups.
