Its state-of-the-art dongle DAC decoding flows onto a fully-balanced analog path counting on common-mode rejection and claiming 131dB of signal-to-noise ratio as a result, for music player levels of detail and fidelity even from USB's 5 volt supply.
A thoroughly regulated circuit and clean power form the basics here, as with every iBasso.
It's solutions like DC04 Pro that continue to see USB DAC/amps raise their game. Further pushing decoding precision is an outboard clock that means DC04 Pro does not rely solely on its USB receiving chip for a master clock, but its FPGA. [See Product Desc. For More]
