iBasso DC04Pro | Hi-Res Balanced Portable DAC and Amp

iBasso DC04 Pro Brings Flagship DAC Technology to an Ultra-Portable

Uses dual Cirrus Logic CS43131 DAC chips for high resolution audio
Surprisingly powerful amplification but with low THD+N distortion and high SNR for the price
Premium finish with Aluminum build
Balanced 4.4mm and single-ended 3.5mm outputs


Flagship-Grade Dual DAC Chipset
iBasso DC04 Pro features a premium Dual-DAC chipset housing two CS43131 high-performance 32-Bit DAC chips from Cirrus Logic. They offer best-in-class performance with ultra-low distortion, and high signal-to-noise ratio performance, and produce a clean output with high dynamic range.
High-Resolution Audio Signal Decoding
iBasso DC04 Pro decodes high-resolution audio signals with support for all leading high-resolution PCM and DSD audio signals. It supports up to 32-Bit/384kHz PCM signals and up to DSD256 signals natively. Simply enjoy true high-resolution audio anywhere with your DC04 Pro!!
Dual Headphone Output Ports (3.5mm + 4.4mm)
iBasso DC04 Pro houses dual headphone output ports. The device provides the user with a single-ended 3.5mm output and a 4.4mm balanced headphone output option. Currently, all leading IEMs and headphones come with either of these two termination options, so the DC04 Pro is compatible with most IEMs and headphones out of the box.
Powerful Amplification Circuit
iBasso has featured high-power amplification circuitry on the DC04 Pro. The device utilizes dual RT6863 amp chips that produce a powerful signal amplification while keeping the THD+N distortion low and high SNR performance.
Exclusively Premium Finish with All-Aluminum Build
iBasso has designed the DC04 Pro with a premium finish. The device has an exclusive unibody build with all-aluminum chassis and tempered glass panel for a solid structure. The DC04 Pro has an elegant finish and looks exquisite as well.

Clean Performance with Ultra-Low-Noise LDO
For high-grade audio products, the quality of the power supply plays an important role in the performance of the said device. The latest DC04 pro features ultra-low noise LDO supply circuit that ensures clean power is delivered to different components on the audio circuitry.

FPGA + KDS Crystal Oscillator
iBasso DC04 Pro utilizes an in-house developed FPGA algorithm. It is supported by a KDS crystal oscillator to form a low-jitter clock on the DC04 Pro. This helps in delivering clear and accurate high-resolution audio signal decoding performance.
