True 24-Bit R2R DAC 

Fully differential four-channel design with 192 precision resistors ensures rich, natural, and musical sound with lower noise and distortion.

Dual NOS/OS Modes 

Choose between Non-Oversampling for authentic, organic sound or Oversampling up to 384kHz for cleaner, more detailed playback.

Preamplifier & Power Amplifier 

Functions as a versatile desktop hub with PCM 384kHz/24bit and DSD256 decoding for high-resolution audio.

10-Band PEQ Equalizer 

Precision sound customization via FIIO Control app or web interface, with presets, headphone correction, and curve sharing.

Fully Balanced Amplifier Circuit 

Differential signal processing across the audio chain for minimal distortion, dynamic range, and pop-noise protection.

Advanced Power Supply Design 

Built-in 30W AC supply with external DC input, multi-rail regulation, and ELNA RA3 audiophile capacitors for stable, clean power.

High Output Power 

2400mW + 2400mW balanced output drives demanding headphones and IEMs with ease.

HD LCD Display 

High-contrast, long-lasting screen shows sampling rate, volume, gain, and output mode at a glance.

Premium Build & Design 

Unibody aluminum chassis with “skylight” RGB lighting blends minimalism with a modern tech aesthetic.

High-Resolution Bluetooth

Bluetooth 5.4 with LDAC, AAC, and SBC codec support for wireless HiFi listening.

Adaptive & Safe Operation
