Product Description


DC03 second generation decoding headphone amplifier line
Witness the decoding line into dual DAC
The era of nanovolt level noise and low distortion
1. Dual CS43131 decoder chips
2. Noise floor <0.9μV is almost inaudible
3. THD+N<0.00028%
4. [email protected]Ω
5. 3.5mm stereo audio interface

1. Open the decoding line dual DAC first, listen to the full and sweet crystal sound
We have carefully crafted the DC03 (40mm*15mm) in the limited size, using two high-performance HiFi decoder chips in a breakthrough, which significantly improves the output power and channel separation, and the details are more abundant.
Cirrus Logic's new generation of CS43131 with MasterHIFI™ technology has great potential and has a sweet and audible sound. The DC03 dual DAC design and double the materials used ensure the high-quality sound of the second-generation decoding amp cable.

2. Real gold is not afraid of fire, hard power is not afraid of PK
Indicators are not the only criterion for verifying sound quality, but they are sufficient to illustrate the level of product design capabilities. The above are all AP measured indicators, which are among the best in decoding line products! SNR 127dB, noise floor <0.9μV, single-ended thrust [email protected]Ω THD+N0.00028% (-111dB), output impedance 0.12Ω dual CS43131, PCM32/384, DSD256, Hi-Res AUDIO

3. Comparison of DC03 with mainstream thousand-yuan HiFi player and first-generation decoding line mainstream thousand-yuan HiFi player
DAC: ES9018Q2C/ ES9218P (single DAC), USB sound card function without computer, signal-to-noise ratio: usually less than 120dB, THD+N: usually no less than 0.004%, noise floor: usually no less than 5μV, single-ended thrust: [email protected]Ω Left and right, output impedance: about 5Ω, does not support online listening to music 1st generation decoding line
DAC: AK4490/AK4493/ (single DAC), can be used as a computer USB sound card, signal-to-noise ratio: 110dB to 120dB, THD+N: about 0.002%, noise floor: usually not less than 3μV, single-ended thrust: [email protected]Ω Left and right, output impedance: about 2Ω, support mobile phone to play online music iBasso DC03 (second generation decoding line) DAC: dual CS43131 (dual DAC), can be used as a computer USB sound card, signal-to-noise ratio: 127dB, THD+N: 0.00028 % (-111dB), noise floor: less than 0.9μV, single-ended thrust: [email protected]Ω, output impedance: 0.12Ω, support mobile phone to play online music.

4. Based on superior indicators, tune out a charming and good sound
The core indicators of DC03 audio are outrageous, with a signal-to-noise ratio of 127dB and a THD+N of 0.00028%, leaving similar products far behind. Even compared with high-end HiFi players, it is not inferior. On the basis of outstanding indicators, DC03 has gone through nearly a hundred tunings, bringing amazing sound.

5. The bottom noise reaches nanovolt level, approaching zero, clean and transparent
In the AP actual measurement, the DC03 noise floor is less than 0.9μV (900nV), which is the best among similar products. The outstanding noise floor control keeps the DC03 clean sound floor, allowing the listener to immerse in the music.

6. The long-lost 3.5mm headphone interface is a little fortunate to regain listening to music on mobile phones
Nowadays, when listening to music with a mobile phone’s 3.5mm interface is becoming more and more luxurious, DC03 relives the beauty of listening to music with wired headphones. Those who insist on listening for a long time do not need to change!

7. Slender body contains surging thrust, listening to music on the phone also requires HiFi to the end
Compared with DC02, the thrust of DC03 has been increased by 3 times, reaching [email protected]Ω, which is even better than mainstream thousand-yuan HiFi players. Earphones that were once difficult to push can also be pushed methodically and clearly on mobile phones.

8. Do not miss every little detail, the experience is satisfactory
The metal shell of DC03 adopts the wire drawing process, which has a delicate look and feel, which is comparable to high-end HiFi players. Selected 4 strands of spiral-wound copper silver-plated fever wire, bringing you a more comfortable experience.

9. From Android phones to computers to meet the needs of all scenarios
DC03 adopts Type-C interface and uses standard UAC2.0 sound card chip. It is not only compatible with most Android phones and tablets on the market, but also can be connected to Apple/Windows computers through the included CA adapter to easily realize external Set decoding. Plug and play, Hi anytime, anywhere.

10. Provide exclusive APK software to achieve 64-level hardware volume adjustment
Mobile phones usually use software algorithms to adjust the volume, usually only about 10 levels. The volume of each level varies greatly and it is difficult to provide fine adjustment. The output level of DC03 is as high as 2Vrms. Even if the volume of the mobile phone is only 1, the volume may be very loud. To this end, we have compiled an APK that supports UAC2.0 volume adjustment to achieve 64-level hardware volume adjustment. Make each level of the phone volume can be subdivided into 64 levels. The volume can be precisely controlled, and the transition is more delicate.


11. Operation introduction DC03 can be plug and play on Android devices with Android 5.1 or higher (affected by the device system or hardware, there may be compatibility differences on a very small number of Android devices). However, because the DC03 output level is as high as 2Vrms, even if the volume is 1 on some Android devices, the volume may be loud. Therefore, it is recommended that you install the dedicated Android APK-iBasso UAC to achieve finer volume adjustment. For some types of Android devices, you may need to manually turn on the OTG function in the system settings. When used with mobile phones, it supports up to PCM32bit/384kHz and Native DSD256 output.

The connection to note10+ can only be recognized after rebooting, and it needs to be reconnected every time it is unplugged. It seems that it will be the case when connecting to Samsung devices such as S10 on Google. I don't know if it can be resolved... Regardless of identification, the "little tail" type of earphones is not bad, of course, don't compare with most DACs. It is purely fresh and fun to connect and listen to the final b1 which hasn't been burned before. Of course, it is different from even DAC.
