K15 Desktop DAC and Headphone Amplifier

The FiiO K15 is a feature-packed all-in-one desktop DAC, streamer and headphone amplifier. It uses dual AKM AK4497S "Velvet Sound" DAC chips and a fully balanced, differential signal path from DAC to amplifier for high channel separation and minimal noise.

• Dual AK4497S DAC setup with fully balanced audio circuitry
• Discrete Class-AB transistor current-boosting headphone amplifier
• Two ultra-low phase noise femtosecond crystal oscillators
• 3,000mW + 3,000mW output power
• 3.93-inch touchscreen display
• Infrared remote control included
• 2.4G/5G dual-band Wi-Fi and Gigabit Ethernet
• High-resolution Bluetooth input with LDAC, AAC and SBC codec support
• Local playback via external USB storage
• Roon Ready and AirPlay 2 streaming
• Independent analogue and digital power supply
• 10-band PEQ
• Multi-layered circuit protection

The K15 can function as a standalone DAC, a dedicated headphone amplifier, a network streamer, or all three simultaneously.

AKM Dual-DAC Chipset

The K15 uses two AKM AK4497S chips — AKM's latest flagship-grade 32-bit DAC. The "Velvet Sound" technology delivers Hi-Res audio processing with ultra-low distortion, wide dynamic range and extended signal bandwidth.

Discrete Class-AB Headphone Amplification Circuit

FiiO's discrete Class-AB headphone amplifier circuit uses an op-amp plus transistor current-boosting design. A pair of ON Semiconductor MJE243G/253G chips provides high-current amplification and low-impedance output, reaching up to 3W per channel.

The low-impedance output suits both full-sized headphones and high-sensitivity IEMs. Five-level adjustable gain makes it straightforward to pair with low- and high-sensitivity audio gear alike.

Fully Balanced Audio Circuitry

Every stage of the K15 — DAC decoding, low-pass filtering, gain control and headphone amplification — uses a fully balanced design. This delivers ultra-low distortion, reduced crosstalk, minimal noise and wide dynamic range.

The K15 supports Roon Ready and Apple AirPlay 2 for network streaming. An Ingeric X2000 processor chipset powers the user interface, and the 3.93-inch colour touchscreen makes day-to-day operation simple. If you are also considering a more compact option, the FiiO K13 is a smaller R2R desktop DAC and headphone amplifier in the same range.
