DAC and Headphone Amp · Streaming Media · Local Playback All in One Unit K15 Is Officially Released!

Following the widespread acclaim of the previous K17, the K15 carries on its retro design and core features, offering a more affordable price point to meet diverse audio experience needs.

The first comes with AKM’s premium DAC AK4497S

The K15 is among the first to use two of the new high-end AKM DAC chips, AK4479SVQ, featuring the 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.

Discrete architecture class-AB transistor current-boosting headphone amplifier circuit

The K15 applies the same highly acclaimed discrete headphone amplifier circuit as the K17, 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, yet melodious sound.

2 Accusilicon low phase noise femtosecond audio crystal oscillators

Inside the K15 is the industry-leading ACCUSILICON ultra-low phase noise AS318-L crystal oscillator (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.

DC/AC dual power supply

The K15 features a built-in next-generation 30W (12V-2.5A) low-noise, high-efficiency, long-lasting, industrial and instrumentation-grade power supply. The K15 also supports external DC power supplies, allowing it to work with higher-performance linear power supplies for even higher sound quality.

For more impressive features, such as the fully balanced audio circuit, touch control+knob control+remote control+FIIO Control App connection, 10-band high-precision PEQ, etc., please visit the product page on our website.
