FIIO K15

The FIIO K15 is a high-quality desktop DAC and headphone amplifier designed for audiophiles who demand both precision and power. Thanks to FiiO's expertise in digital audio, the K15 delivers a pure and detailed sound character, with support for hi-res audio formats so that music is reproduced with impressive accuracy. With a powerful amplifier section, it can effortlessly handle everything from sensitive in-ear monitors to demanding planar magnetic headphones, offering versatility for any setup. With its sleek design, extensive connectivity options, and FiiO's commitment to high-quality engineering, the K15 is the perfect centerpiece for both desktop and home listening setups.

Premium AKM DACs

The K15 is among the first devices to integrate two of AKM's top-of-the-line DAC chips, the AK4479SVQ, equipped with advanced VELVET SOUND audio technology. These DACs deliver exceptionally low distortion, a wide dynamic range, and an extended signal bandwidth, while keeping power consumption low. This allows the K15 to preserve rich details in both low and high frequencies, resulting in a natural and immersive listening experience.

Discrete class-AB

Like the highly acclaimed discrete headphone amplifier of the K17, the K15 utilizes an OP+ transistor current-boosting architecture. At its core is a complementary pair of ON Semiconductor's classic MJE243G/253G transistors, which provide high current delivery and low output impedance. This discrete circuit delivers balanced output power up to 3000mW + 3000mW, allowing the K15 to effortlessly drive both full-sized headphones and sensitive in-ear monitors – with a sound that is smooth, natural, and musically compelling.

Clean and stable sound

For clock synchronization, the K15 is equipped with ACCUSILICON's industry-leading AS318-L crystal oscillators with ultra-low phase noise (45.1584 MHz, 49.1520 MHz). These oscillators significantly reduce phase noise interference in audio signals, ensuring accurate reproduction across a wide range of sampling rates, resulting in cleaner and more stable sound.

DC/AC power supply

The power supply consists of a next-generation 30W (12V–2.5A) high-quality industrial power supply with low noise, high efficiency, and long life. For those who want even better performance, the K15 also supports external DC power supplies, allowing it to be combined with high-quality linear power supplies to further optimize sound quality.
