IBASSO INTRODUCES DC03 PRO, A WORTHY UPGRADE TO THE WIDELY POPULAR DC03
iBasso is a well-reputed brand in the industry. They are mainly known for their wide range of portable audio gears, including IEMs, USB DAC/AMPs, DAPs, etc. The DC03 was a "great" portable USB DAC & Amp that took the industry by storm. It garnered high-level praise from the audiophile community. iBasso wanted to continue the spree and develop something "powerful" and "durable," which gave birth to DC03PRO. The DC03PRO is a worthy upgrade and packs a punch with its extraordinary performing capabilities. With premium CS43131 DAC chips from Cirrus Logics, the DC03PRO brings flagship-level performance to your smartphones. For "clear" and "accurate" audio signal decoding, a high-performance KDS femtosecond crystal oscillator is incorporated into its design. DC03PRO offers a high-quality experience by supporting high-resolution PCM and DSD signals!
DUAL CIRRUS LOGIC DAC CHIP AND KDS OSCILLATOR DELIVER SPECTACULAR PERFORMANCE
The Cirrus Logic CS43131 dual DAC chips, which are of the highest calibre and provide unmatched digital-to-analogue conversion, are found in the DC03PRO. With Master HiFi™ technology, the flagship DAC from Cirrus Logic offers "amazing" performance and fantastic sound. With iBasso's extensive investment in research and development and well-selected parts, the DC03PRO is a "wonderful" and affordable standout USB DAC & Amp. iBasso DC03PRO promises ultimate high-resolution audio performance with its flagship dual DAC arrangement supporting PCM (Pulse Code Modulation) up to 32bit/384kHz and Native DSD (Direct Stream Digital) up to 256x. iBasso has featured dual CS43131 DAC chips that enable the DC03PRO to achieve class-leading performance with ultra-low distortion and high SNR ratings. CS43131 is a premium 32-Bit DAC supporting 32-Bit Hi-Res signal decoding. The DC03PRO hosts a KDS femtosecond oscillator, which reduces phase noise and provides a more accurate clock reference for the DAC. The DC03PRO brings pure and transparent music replay.
LOWER POWER CONSUMPTION WITH NANOVOLT LEVEL NOISE FLOOR
iBasso has designed the circuitry of the DC03PRO with utmost precision. The noise floor on the DC03PRO reaches the nanovolt level and provides a blacker background. Generally, the noise floor of many audio players and similar dongles is between 3-10uV. In the AP measurement, the noise floor of DC03PRO is less than 0.9uV (900nV), which stands out among similar products. Every moving melody and note in the music seems to emerge in space free of distracting low-level noise. The DC03PRO measurements are full of highlights. Even compared with the much more expensive dongles, the DC03PRO measurements are outstanding. The DC03PRO utilises an industry-leading power management chip to intelligently control power consumption and an asynchronous DC-DC converter, which minimises power consumption. When compared to other dongles that usually have 600mW or above power consumption, the DC03PRO saves 36% power for your smartphone or other sources.
WIDE COMPATIBILITY WITH SOURCES AND SUPPORT FOR COMPANION APP
The iBasso DC03PRO adopts a type-C interface and uses a standard UAC2.0 sound card chip, which is not only compatible with most Android phones and tablets in the market. It also can connect to a Windows PC and Mac to become a USB DAC. It is also compatible with Mac/Windows computers through the C-A adapter, realising external decoding. It also has an interchangeable cable design for adaptation and easy plug-and-play functionality. The iBasso DC03PRO supports the latest version of the UAC application with advanced features. It has five optional digital filters, three gain levels, 100-level volume adjustment(using hardware keys), different EQ functions, two options for output mode, and 20 steps L/R balancer. The DC03PRO has a detachable cable design and comes standard with a USB-C to USB-C cable compatible with most Android devices. The DC03PRO can be used with iOS devices when connected with a USB-C to lightning cable (separately purchased). You will feel completely immersed in whatever you're doing, whether watching a movie, playing a video game, or listening to music—the unlimited entertainment provided by outstanding sound will only enhance your experience!
CNC ALUMINUM CASE WITH TEMPERED GLASS PANELS FUSED WITH UNPRECEDENTED SPECS OF SINGLE-ENDED PERFORMANCE
The DCO3PRO case is made from a solid piece of CNC-machined aluminium alloy. The hollow design of the volume guard requires complex steps during machining to achieve its good form and function. With the tempered glass panels, the DCO3PRO is visually appealing and conveys the quality of its build. Silver, Grey, and Blue colours are available to meet individual preferences. iBasso has included a 3.5mm stereo output, which enables you to turn your smartphone into a Hi-Res audio player. The lack of many smartphones to work as high-quality music players is transformed by the DCO3PRO. The DCO3PRO was born for HiFi enthusiasts who are accustomed to listening to music on smartphones and wish to have no compromise on sound quality. The 3.5mm universal interface has excellent compatibility, convenience, and support. The iBasso DC03PRO also has a multi-colour indicator that indicates various operation modes: Red - Standby, Blue - DSD, and Green - PCM.

I'm a first time DAC buyer and I dont know fancy audiophile language . So do forgive my layman language.
Gear : using iBasso DCO3 Pro with Note 20 and ATHM50X or Presonus 3.5 BT(over aux).
This is an early review after only a few days of use.
Gotchas - Make sure your phone audio-quality effects are all turned OFF. Phone's Dolby atmos are turned OFF, graphic equalizer presets are all set to flat.
Build and features - Its well built and feels unbreakable. BUT. do take care to not unplug this along with your headphone wire. Its likely get banged around along with the dangling wire. Should be avoided to avoid needless abuse of the tiny device.
The iBasso UAC app provides a few tuning options like Gain, 100 step volume and filters. Honestly other than the volume and Gain, i have no idea how to use the filters. I'm not able to make any discernable difference in music between the filter settings.
Input quality - I use Apple Music Hires lossless settings and it plays music with a minimum lossless quality. Not all content is available in Hires Lossless.
Performance - I used to think Macbook Pro and iPad DACs were solid. This goes above and beyond! Be prepared to shocked if all your old songs sound different. It somehow boosts all instruments /sounds to the same level as vocals and yet maintains clear separation. So if there are some techno sounds going non stop in the background when ARR is singing Mental Manadhil (Ok Kanmani) it will sound much more prominent than it used to. All the sounds are brass tack sharp and brighter now. The vocals too. I dont notice bass getting muddy. In fact its muted and to my liking. My ears are sensitive to bass and i dont notice it much (at least in my gear) . Its like salt. Its present but you dont notice it.
The clear separation of all sounds is what makes the music enjoyable. So if you are hearing the sitar in Aaj Ibadat (Bajirao Mastani) along with the bass and some chorus. The sitar will be crystal clear and sharp and will not be muddied by the bass or other sounds. That's what makes it enjoyable.
I did not notice any change in temperature of the unit even after 1 hour.
Overall its worth the money paid for it. I'm sure there are better gear but this is the only one i've listed to and i like it.
The subject matter expertise that reflects in the headphonezone website is what gives the confidence in buying from this site. This is my first purchase from them.. I'm now convinced that this is the place to go to and I'll probably tell my friends to buy from here when opportunity presents.
I'm glad that my first shot at a DAC is turning out to be a good experience. Thank you headphone zone.
This little thing is reference quality to me. Drives even the akg k712 effortlessly. The size belies its quality. Details and soundstage are top notch without ever sounding analytical. Timbre, soundstage musicaliyare top notch. Gor the proce a steal especially for iems. Dead quiet in sensitive iems too
I liked it very much sound quality is great with the dac
Hey Puneet, thank you so much for the awesome review!
It is very good looking and has a great sound experience using it
Hey there, thank you for the awesome ratings!
Firstly I would like to thank Virendra -headphone guru. I initially ordered another Dac which was not compatible with my iPhone or 3.5 mm headphone jack. I had to return those . I got excellent guidance from Virendra who recommended me to check ibasso with a proper adapter . Kudos to the excellent team handling the return and delivery of the products ordered.
Coming to this product - this sounds awesome even with normal volume and doesn’t drain the battery much . I am very happy with this product and for iPhone 12 /13 users this will work 100% with the adapter available and it works excellent with my windows laptop as well
Hey Anirban, Thank you so much for the positive feedback! It means a lot to us. We are so happy to hear that you are loving our products and services.
Excellent...Excellent. My smart phone is now a small sound studio also. Smooth sound at low volume in a silent atmosphere!... Please download the app also. Some settings are there. It will help to improver the sound quality.
We really appreciate the genuine feedback. We'll share your thoughts with the brand as well!
