FiiO Introduces A Flagship-Grade All-in-One DAC & Amp - The K15
Step into a new era of high-fidelity desktop audio with the FiiO K15, a feature-rich all-in-one DAC and headphone amplifier built for serious audiophiles. As one of the first to adopt dual AKM AK4497S DAC chips with enhanced VELVET SOUND technology, the K15 delivers low distortion, wide dynamic range, and lush musicality. With powerful Class-AB amplification, 8 versatile playback modes, and advanced streaming support including Roon Ready, AirPlay and Bluetooth LDAC, the K15 is engineered for versatility and precision. Whether you're driving power-hungry headphones or fine-tuning your sound with onboard PEQ, this fully balanced, precision-built desktop unit offers everything you need for an uncompromised listening experience.
Features Dual AKM DAC With VELVET SOUND Tech For Hi-Fi Sound
FiiO K15 is among the first to feature dual high-end AKM AK4497S DAC chips, enhanced with AKM’s upgraded ‘VELVET SOUND’ technology. This audio architecture ensures low distortion, ultra-wide dynamic range, extended signal bandwidth, and impressively low power consumption. As a result, it delivers a natural and immersive sonic experience with rich detail from low to high frequencies. VELVET SOUND embodies AKM’s philosophy of achieving true-to-life sound through refined engineering and uncompromising acoustic realism.
Equips Discrete Class-AB Headphone Amplifier for Powerful Output
FiiO K15 incorporates a fully discrete headphone amplifier circuit based on an OP + transistor current-boosting design. A complementary pair of ON Semiconductor MJE243G/253G transistors ensures high current, low impedance output. This setup provides a balanced output power of up to 3000mW + 3000mW, enabling the K15 to effortlessly drive both demanding full-sized headphones and sensitive in-ear monitors, producing a smooth, melodious, and natural sound signature.
Offers Eight Versatile Operating Modes For Tailored Listening Needs
Note: Portable hard drives may require external power.
Embeds Fully Balanced Circuit With Physically Isolated Boards
FiiO K15 employs a fully differential design from DAC decoding to headphone amplification. This architecture ensures wide dynamic range and significantly reduces crosstalk and noise, elevating overall audio purity. Digital, analog, and power sections reside on separate physical boards to ensure signal integrity. Two Accusilicon low phase noise femtosecond crystal oscillators (45.1584MHz and 49.1520MHz) ensure ultra-precise signal reproduction across all sampling rates for stable, high-fidelity playback.
Robust Power Supply Design for Maximum Isolation and Purity
FiiO K15 features a built-in next-gen 30W (12V-2.5A) industrial-grade power supply, supporting ultra-wide 85–305VAC input voltage and extreme operating temperatures (-40°C to 85°C). It also accepts external 12V-2.5A DC power inputs, including high-performance linear supplies for enhanced audio performance. A precisely segmented multi-stage analog power section handles DAC, LPF, and amplifier stages, using up to 14 low-dropout regulators to ensure clean, stable power delivery.
Fused With Premium Components for High-End Performance
FiiO K15 integrates high-quality components for an extraordinary performance. It features 8 Ruby Film Capacitors + 32 Wafer Resistors: Low noise and temperature stability for consistent performance. The 2 Nichicon 3300µF + 4 ELNA MILIC II + 8 ELNA RA3 Capacitors provides rich sound with enhanced stage depth. It utilises Beryl Capacitors for ultra-low ESR and excellent anti-interference properties. K15 is fused with silver-plated oxygen-free copper wires to ensures minimal signal loss across internal board connections.
Utilises Dual Master Processors For Smooth And Stable Operation
FiiO K15 is equipped with the high-performance multi-core X2000 processor featuring dual XBurst\@2 cores and a micro-core for low-power, high-efficiency audio processing. Additionally, the ESP32-S3 MCU includes a dual-core Xtensa 32-bit LX7 and an ultra-low-power coprocessor clocked up to 240MHz, ensuring seamless system control and snappy user interactions.
Features 10-Band PEQ For Precision & Tailored Tuning
FiiO K15 includes a 10-band high-precision PEQ on all digital input modes (USB, optical, coaxial, Bluetooth, streaming, and local). Users can simulate and adjust the frequency response of connected headphones using FiiO’s web-based PEQ tool, making it easy to fine-tune the sound to personal preference.
Seamless Connectivity With Wired & Wireless Compatibility
FiiO K15 offers a comprehensive suite of connectivity options like USB Decoding, Streaming via Roon or AirPlay, Local USB Playback, Optical/Coaxial Decoding, Single-Ended & Balanced Analogue Inputs and Bluetooth Wireless Decoding.
Fast & Stable Wired Transmission & Supports FiiO App Control
FiiO K15 includes a Gigabit Ethernet port for fast, stable wired transmission and an AP6256 Wi-Fi module supporting 2.4G and 5G bands, ensuring seamless wireless playback of high-resolution audio. The K15 can be controlled by the FiiO control app. Note: FiiO Control app is available for Android & iOS
Meticulously Crafted For Impeccable Aesthetics & Extensive Protection
