Premium Audio Conversion Architecture
At the heart of the system lies a dual-DAC configuration featuring AKM AK4497S chips. These flagship converters work in tandem with a fully balanced audio circuit to ensure maximum channel separation and a near-silent noise floor. This architecture is supported by dual femtosecond crystal oscillators, which provide ultra-precise clocking to eliminate jitter and preserve the integrity of high-resolution audio.
Discrete Class-AB Amplification
The device features a sophisticated Discrete Class-AB headphone amplifier equipped with transistor current boosting. This design delivers the raw power needed to drive demanding high-impedance headphones while maintaining the warmth and musicality associated with Class-AB topologies. To maintain signal purity, the internal layout uses silver-plated oxygen-free copper wiring and high-grade capacitors throughout the signal path.
Versatile Eight-Mode Operation
This unit serves as a comprehensive "all-in-one" hub for any audio setup. Users can choose from eight distinct operating modes, including:
-
Streaming & Local: Roon Ready, AirPlay, and USB storage playback.
-
Digital Hub: USB DAC, Bluetooth decoding, Optical, and Coaxial inputs.
-
Analog Integration: Both Single-ended and Balanced line inputs for external preamps or turntables.
Isolated Power and Circuitry Design
To prevent electromagnetic interference, the system utilizes physically separated circuit boards for power, digital, and analog sections. Power is managed by a built-in industrial-grade supply, further refined by a multi-stage analog power supply featuring 14 LDO regulators. For enthusiasts seeking the cleanest possible energy, the unit also supports an optional external DC power input.
Intelligent Control and Protection
The user interface is powered by a dual-core X2000 processor and an ESP32-S3 MCU, ensuring smooth performance across the touchscreen, physical knobs, and the FiiO Control App. For fine-tuning, a 10-band PEQ is available on all digital inputs. Finally, a comprehensive suite of protection systems (covering temperature, overvoltage, and DC) ensures the longevity of both the device and your connected headphones.
