iBasso DC04 Pro

$159 $199

The mobile revolution continues as driven by iBasso Audio. DC04 Pro is their latest balanced 4.4mm dongle supplied by the dual Cirrus Logic CS43131 DAC chips from the DX170 music player, working controlled by iBasso FPGA-Master technology.

It's a Headfonia Recommended Buy, and it ticks all the boxes as a complete solution to Audiophile-Heaven. iBasso's flagship dongle is one of 2023's best to eCoustics. It represents the progress dongles have made to ichos-reviews and MOONSTAR Reviews.

DC04 Pro's state-of-the-art decode flows onto a fully-balanced analog path counting on common-mode rejection and claiming 131dB of signal-to-noise ratio.

Music player levels of detail and fidelity even from USB's 5 volt supply are possible with DC04 Pro. 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]

Product Description

Said FPGA sees DC04 Pro overachieve by supplying its CS43131s DACs the same pure I2S as iBasso's bigger DX170, DX240 and DX320 DAP alternatives, pushing down DAC phase noise and jitter for a stable decode.

After decoding, iBasso's generous use of negative feedback quashes distortion and claims up to 131dB of signal-to-noise ratio.

The employment of this feedback also sees DC04 Pro achieve bandwidth that's extended from 20Hz to 40Khz. That means phase reproduction in the audible human hearing region is well preserved, for a realistic portrayal of dynamics and natural transparency – a triumph of iBasso's flagship DAC dongle.

Powerful op-amp output buffers can supply 100mA of current and mean iBasso's little wonder promises high damping factor while maintaining its low distortion into low impedances typical of IEMs, Focals, Fostexs and Rosson Audio Designs.

Still the closed-loop internal gain remaining after the application of negative feedback around DC04 Pro's op-amp IC analog circuit remains high. So where she really shines is in swinging 10 volts, opening up the sound of any high-impedance Audio-Technica, Sennheiser and ZMF Headphones while barely breaking sweat.

The quality of DC04 Pro's signal will translate to nearly everything you choose to drive from its balanced 4.4mm output, or 3.5mm – turning it into a miniaturised DX170, if you would.

Flying the dongle DAC/amp flag high is DC04 Pro, till you turn to iBasso Audio's other upgrades here, or others in our catalogue here.
