Hardware & Software Features:


Digital to Analog Converter (DAC) & Amplification (AMP) Sections:

The iBasso DC06 PRO features a dual ES9219C 32-bit stereo DAC chipset that supports a patented 32-bit “HyperStream” architecture, which enables PCM up to 32-bit 384 kHz and native DSD256 decoding. The DC06 PRO has a SNR of about 120 dBA over the 3.5 mm SE output, while the 4.4 mm Balanced output offers values of 123 dBA. The THD-N of the device is approximately 0.00056% over the 3.5 mm SE output, while the 4.4 mm Balanced out has an even lower value of just 0.00035% at 600 Ω load.

The iBasso DC06 PRO is equipped with a powerful amplifier section that offers of up to 320mW @ 32Ω over the 4.4mm Balanced interface, which is quite impressive for such a compact device. Another highlight about the AMP section is that it utilizes its own dedicated power supply. This includes a synchronous DC-DC converter, a low noise charge pump chip, and an LDO. These implementations enable the AMP section to operate at its maximum capacity without any interference from the digital section. This enhances the dynamics, bass response, and overall transparency of the device.

Moreover, the DC06 PRO comes with an in-house developed FPGA algorithm, which is supported by a NDK Femtosecond oscillator to form a low-jitter clock. This feature helps the DC06 PRO in delivering clear and accurate high-resolution audio signal decoding performance.

The Sound:

The iBasso DC06 PRO is a portable DAC/Amplifier dongle that delivers a refined and balanced sound across the frequency spectrum. It has a tight and authoritative bass, a clear and detailed midrange, and a smooth and airy treble. It also offers a wide and precise soundstage, creating a natural and immersive listening experience.

This review was been written after a burn-in period of about 60 hours. I have paired the iBasso DC06 PRO with sources like the Samsung Galaxy S22 Ultra and the Asus TUF FX505DU. My sound impressions below are mainly based on my experiences with the iBasso IT07, iBasso AM05, Campfire Audio Supermoon and Westone Audio MACH80 IEM’s and the iBasso SR2, HiFiMAN Edition XS Headphones.


The iBasso DC06 PRO’s bass exhibits commendable control and refinement. Sub-bass frequencies rumble with authority, adding weight and gravitas to Daft Punk’s “Doin’ it Right” and Bear McCreary’s “Valkyries” without bleeding into the lower midrange when paired with IEM’s like the iBasso IT07 and Campfire Audio Supermoon. The attack and decay of bass notes are precise, such like in songs like Lorde’s “Royals” or Bear McCreary “Valkyries”. Nuances in bass lines, like the walking bass in Gogo Penguin’s “Raven,” are rendered with admirable clarity.

The DC06 PRO avoids overemphasizing bass, favoring a neutral balance that complements the overall sound signature. It is delivering impactful bass kicks with IEM’s and Headphones I have listen when the music demands, as evidenced by Michael Jackson’s “Billie Jean.” Mid-bass frequencies are natural and well-articulated, providing a solid foundation for instruments like acoustic guitars, cellos and with a wide range of percussions.


The iBasso DC06 PRO shines with its decent performance while handling vocals. Norah Jones’s voice in “Come Away With Me” floats effortlessly, brimming with detail and emotion with the IT007 and HiFiMAN Edition XS. Adele’s powerful voice in “My Little Love” retains its rawness and character without becoming harsh or fatiguing. Male vocals are equally well-represented, with Sting’s rich baritone in “Englishman in New York” and Eric Clapton’s smooth delivery in “Wonderful Tonight” coming through vividly.

The midrange isn’t solely the domain of vocals. Instruments are presented with impressive accuracy and separation, allowing for easy identification of individual timbres and textures. In
In Gogo Penguin’s “Murmuration,” intricate melodic lines emerge from the interplay of piano, drum, and cymbal notes. Tchaikovsky’s Symphony No. 5 similarly presents the distinct separation of violins and brass instruments within the orchestral texture. This characteristic highlights the iBasso DC06 PRO’s ability to render complex arrangements with clarity and precision, a key aspect of its sonic character.



The iBasso DC06 PRO’s treble range shows a good balance between brightness and control. It exhibits an extended and airy character, adding sparkle and detail to instruments like woodwinds and percussion across the IEMs and headphones tested. However, this extension avoids harshness or sibilance, even in energetic tracks like Metallica’s “Sad but True” and Megadeth’s “Sweating Bullets.” While paired with the iBasso IT07 or SR05, the treble remains smooth, while the AM05 might exhibit a slight hint of sibilance and sharpness in certain tracks.

Overall, the smooth rendering preserves the natural character of instruments while maintaining detail. Furthermore, the DC06 PRO’s treble contributes to a spacious and airy soundscape. Delicate high-frequency chimes and ethereal textures unfold seamlessly, enhancing the sense of immersion.


Soundstage & Imaging:

The DC06 PRO delivers a surprisingly expansive soundstage for a portable device. Instruments are positioned with pinpoint accuracy within the sonic space, creating a natural sense of directionality. Bear McCreary’s “The Lord of the Rings: The Rings of Power OST” album benefits from this precision, with each instrument occupying its own distinct space, contributing to the live atmosphere. This is evident in orchestral recordings where layers of instruments are presented with clear separation and positioning, building a pretty natural orchestral space.



iBasso DC06 PRO versus Hidzs XO:

In a head-to-head comparison, the iBasso DC06 PRO and Hidizs XO both offer high-resolution audio decoding and commendable performance, their approach to sound reproduction reveals nuanced differences.

The iBasso DC06 PRO prioritizes precision and control. Its bass delivery is linear and clean, meticulously revealing the intricacies of low-end frequencies without muddying the soundscape. In contrast, the Hidizs XO leans towards a slightly warmer signature, emphasizing the low-end presence. While enjoyable, it may slightly obscure the definition of bass notes compared to the DC06 PRO.

The iBasso DC06 PRO shines in its transparency. Vocals emerge with captivating clarity, each inflection faithfully brought to the forefront. This transparent presentation allows the music’s soul to resonate without undue harshness or thinness. While the Hidizs XO boasts a tad warmer and emotive midrange, it can lose some resolution in complex passages, leaving the listener wanting for that extra layer of detail that the DC06 PRO delivers.

The iBasso DC06 PRO shows a decent balance between brilliance and authority in its treble response. It gracefully extends high frequencies, offering a pretty airy and open soundscape. The Hidizs XO maintains a controlled treble, but it sounds a bit digital and dry in direct comparison to the DC06 PRO.

Both devices offer a decent sense of soundstage width, depth and height. However, the iBasso DC06 PRO distinguishes itself again with a more precise and well-defined sense of depth. While the Hidizs XO can feel slightly congested at times, its soundstage remains adequate for most listening scenarios.



The iBasso DC06 PRO emerges as a compelling choice for audiophiles seeking a portable high-fidelity listening experience. Its refined and balanced sound signature, encompassing tight bass, clear midrange, and airy treble, delivers a natural and immersive sonic landscape. Coupled with its impressive technical specifications, including dual ES9219C DAC chips, dual headphone outputs, MQA rendering, and dedicated power supply, the DC06 PRO punches above its weight in the ultra-portable DAC/Amp market. Whether you’re a seasoned audiophile or a discerning listener seeking a significant upgrade around the 100 – 150 USD price range, the iBasso DC06 PRO is a worthy contender, offering exceptional sound quality, versatility, and convenience in a compact and robust package.


Pros & Cons:

  • + Refined and Balanced Sound Signature
  • + Overall Clarity and Resolution
  • + Ultra Clean Background
  • + Look and Fell (Design & Build Quality)
  • + Dedicated APP for Fine Tuning (iBasso UAC APP)
  • + MQA Rendering
