Not just a DAC/Headphone AMP
FiiO K15 is a highly versatile device that can be used in multiple use case scenarios. This includes using the device as a USB DAC, Wireless Bluetooth DAC, Headphone Amplifier, Network streamer, local playback, and a complete all-in-one solution as well. We are pretty sure the FiiO K15 perfectly fits in every setup!
Dual AKM DACs
FiiO K15 is among the first to use two of the new high-end AKM DAC chips, the AK4479SVQ featuring upgraded 'Velvet Sound' audio technology. The chips achieve low distortion, a wide dynamic range, and extended signal bandwidth, all at low power consumption. Rich detail is retained in both low and high frequencies for a natural and immersive sound experience.
Class AB Amplification
Within the K15 is a carefully designed discrete headphone amplifier circuit, featuring an OP + transistor current-boosting design. A complementary pair of the classic ON Semiconductor MJE243G/253G delivers high current and low impedance output. This discrete circuit can achieve balanced output power up to 3000mW + 3000mW, allowing the K15 to effortlessly drive both full-sized headphones and in-ear monitors, producing smooth, natural, and melodious sound.
Fully balanced design
From DAC decoding, low-pass filtering, and gain control to headphone amplification, the K15's audio circuit is a fully differential design. Such a design ensures wide dynamic range while also effectively reducing crosstalk, minimizing noise, and enhancing the quality of sound.
Low jitter clock
Inside the K15 are dual ACCUSILICON ultra-low phase noise AS318-L crystal oscillators (45.1584MHz, 49.1520MHz) that effectively reduces phase noise interference in audio signals. This ensures precise reproduction of audio signals at various sampling rates, for purer and more stable sound.
