The DX320 is a great music player from iBasso that includes dual ROHM DAC chips, a dual battery system for the analogue and digital sections, dual Android 11 and Mango OS, and much more. Featuring a large and vibrant screen, the DX320 is also backwards compatible with DX300-series amp cards.

Dual BD34301EKV Era

The BD34301EKV DAC chip, developed as a part of ROHM’s high-grade MUS-ICTM series representing the pinnacle of audio ICs, emphasizes ‘spatial reverberation’, ‘quietness’, and ‘dynamic range’ - qualities important for reproducing all music. Original sound quality design technology makes it possible to successfully reproduce the targeted natural reproduction of sound. At the same time, a class-leading low noise and distortion (130dB SN ratio, -115dB THD+N) provides the high performance demanded by high-fidelity audio equipment.

On the DX320, iBasso has carefully designed circuitry and implementation of this DAC to allow all the quality of the BD34301EKV to shine through. With more than ten years of tuning and design experience and the persistent pursuit of technological innovation, the new flagship DX320 is a product based on the excellent performance of our past generations of DAPs!

In-House Developed FPGA-Master - A Dedicated Controller of the Audio System

In the DX320, iBasso adopted an in-house developed FPGA-Master technology. The FPGA-Master, as the audio system controller, directly requests audio data from the SoC, and plays a major role in signal reproduction and maintaining signal integrity. It synchronizes and generates all audio clocks at the same time utilizing two Accusilicon femtosecond oscillators, to achieve a fully synchronized single clock source. The FPGA and oscillators also reduce jitter to an extremely low level, building an exceptionally clean digital audio signal. Android audio processing does not have high system priority. The addition of FPGA-Master technology raises audio scheduling to the system’s highest priority processing sequence, creating a stable and interference-free digital audio system for the DX320.

Patented Dual Battery Power Supply Structure - Separate AMP & Digital Power Supplies

The power system is one of the most significant parts of a player and has a decisive influence on sound quality. SoC, DAC, AMP, and other components all have strict requirements for transient power supply. When a single battery is powering the entire system, a large demand of current by the digital section and the analogue section can affect each other, which can cause distortion degrading the sound quality. The DX320 utilizes a patented dual battery structure with the AMP and digital section being powered by independent batteries. The independent battery provides a sufficient power supply to ensure the stability of the AMP section and it isolates the digital section interference to achieve better overall sound quality. This ensures that the analogue section is receiving extremely clean DC, allowing the AMP section of the player to evolve to its full potential.

14nm 8-core Qualcomm Snapdragon 660 6G RAM +128G ROM - As Smooth as Using a Smartphone

The DX320 is equipped with Qualcomm Snapdragon 660 as the SoC. With the powerful performance of this 14-nanometer 8-core processor, the operation is outstanding in the field of digital audio players! With 6GB of RAM there is ample memory for a consistent and fast response, and the 128GB of onboard storage space allows for the convenience of installing more Apps and Music.

Replaceable AMP Card - Free to Define

A replaceable AMP Card Design provides for more variety, personalization, and enjoyment of your music. Currently, there are discrete AMP cards: AMP11 MK2, and super-class A discrete balanced AMP card AMP12, in addition, Nutube AMP card AMP13 will also be listed soon. There is no need to replace the player, just replace the amp card and you can freely switch between the transistor with sharpness and crispness based AMP and the vivid tube sound quality.

Note: When using AMP12 with DX320, it is recommended to select medium or low gain. Due to the circuit design compatibility, the AMP12 has a certain noise floor at height gain.

Discrete AMP Card AMP11 MK2s Sound Supreme

The Default AMP card AMP11 MK2s is based on AMP8’s discrete circuit and is equipped with 3.5mm single-ended, 2.5mm balanced and 4.4mm balanced outputs ports (all ports can also be changed to line outputs). A +/18V power supply provides sufficient and stable energy for the AMP section. The maximum output current of the transistor reaches 2A, which allows the AMP11 MK2s to drive IEMs and headphones that require high current with ease. The maximum voltage output of DX320 reaches 7.1Vrms, and thanks to the independent battery power supply, the maximum output power of 32 Ohms load is as high as 1200mW! In order to have the best match with the DX320, the AMP11 MK2s were tuned with some electrolytic and film capacitors, including the new custom iBasso Premium AI foil audio capacitor.

Excellent AP Measurements - Outstanding Flagship Sound Performance

In the core measurements, the DX320 is also excellent. The measured signal-to-noise ratio is 125dB, the dynamic range is 125dB, and the THD+N is -112dB. With these good measurements, the foundation was laid for its flagship sound. The maximum voltage output of the DX320 balanced output is 7.1Vrms, and it effortlessly drives most all full-size headphones! The output power with a 32 Ohms load reaches 1200mW, which is very high among portable DAPs.

Android 11 + Mango OS Open Android & Closed Linux OS

The DX320 is equipped with the up-to-date Android 11 OS. The faster system response and smoothness rank the DX320 at the forefront of the HiFi players. You can freely install most Apps and enjoy online streaming. As with previous iBasso players, the DX320 bypasses the SRC from the system level, whether it is the built-in Mango player or the third-party streaming APK, you can enjoy the system-level “Non-SRC” feature. At the same time, the DX320 has a Linux-based system specifically developed for pure audio playback, the Mango OS. With the powerful GPU acceleration of Qualcomm 660, the fluency of the Mango system is close to that of Android. This Mango OS has accumulated a lot of optimization results for music decoding and underlying driver algorithms. Also, Mango OS disables Bluetooth and WiFi to reduce EMI interference. It has also minimized the CPU and RAM usage to maintain the system's purity to achieve sound quality.


MQA (Master Quality Authenticated) captures 100% of the original studio performance and then folds the file to make it small enough to stream. The DX320 includes MQA technology, which enables you to playback MQA audio files and streams, enjoying the sound of the original master recording.

Bluetooth 5.0 + 5G WiFi 2x2 MIMO Speedy & Carefree Wireless Experience

With an upgraded internal antenna, the DX320 gives you great coverage. The 5G WiFi adopts a 2x2 MIMO WiFi antenna design, with two input and two output channels, resulting in the data transmission speed and data volume being greatly upgraded. The DX320 supports Bluetooth 5.0, with an enhanced antenna that gives a longer transmission distance and a stronger signal.
