■Powerful driving performance of the highest peak in its class

The newly installed "Desktop mode" achieves the highest output of 650mW in its class with balanced output. Adopts four op-amps installed in THX's headphone amplifier AAA-78+ to powerfully drive high impedance headphones. It expresses the sound source dynamically and delicately.

■Designed to pursue the ultimate sound quality

-Equipped with two low-power, high-performance ESS DAC chips "ES9069Q", as well as the same "THX AAA-78+" circuit as THX's headphone amplifier AAA-78+ and an independent USB Type-C port for power supply. This reduces noise to the utmost and achieves stable high output. We pursued overwhelming high sound quality through a precise power supply circuit design and a board configuration that completely separates the analog and digital circuits.

■Evolved sound quality adjustment and wide range of sound source support
-FIIO's unique PEQ algorithm provides a 10-band high-precision PEQ function. You can finely adjust the gain and bandwidth from the dedicated app "FIIO Control" and tune to your preferred sound quality. The 16-core high-speed processing USB interface chip "XMOS XU316" supports various high-resolution sound sources such as PCM768kHz/32bit, DSD512/1bit, and MQA full decoding.

■ Excellent operability and safe design
- Equipped with a 0.91-inch dot matrix display with excellent visibility, it displays many statuses clearly. In combination with hardware buttons, it allows intuitive operation. The multi-protection system provides a safe listening environment with temperature protection, DC output protection, and volume limit setting.

■ Various connectivity and high portability
- In addition to 3.5mm/4.4mm dual headphone output, it also supports S/PDIF digital output from 3.5mm and can be used as a DD converter. UAC1.0 support allows it to be used with a wide range of devices such as game consoles. Comes with a highly designed dedicated leather case, making it ideal for outdoor use. The metal case combines excellent design with ease of use.
