The iBasso DX300 is the fully evolved new flagship music player from iBasso. The DX300 is a reference digital audio player (DAP) that houses dual system controllers along with dual batteries. The 6.5inch near-bezel-less screen is incredibly sharp and vibrant with an ultra-HD resolution of 2340x1080.

The DX300 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 analog section receives extremely clean DC, allowing the AMP section to perform to its fullest. When a single battery is powering the entire system, a large demand of current by the digital section and the analog section can affect each other, which can cause distortion, that ultimately degrades the sound quality.

A feature of the DX series is the replaceable AMP card design. AMP cards provide for more variety, personalization, and enjoyment of your music. You can change output port configuration, circuit design, play time, and much more. The DX300 music player features the Octa-Core Qualcomm Snapdragon 660 mobile platform, 5th Gen Mango OS + Android 9.0 OS, 6GB of RAM, 128GB internal storage with external expansion option, and Quad CS43198 DAC chips, the current flagships from Cirrus Logic.

Design Overview

4pcs CS43198 DAC, 2 batteries one for Digital and one for Analogue. Our own FPGA chip and the Snapdragon 660 for Two controllers. Android 9 OS, 6.5inch capacitive full screen. Stock AMP11 module is 2.5,4.4,3.5 and all can be used for line out. The back is a matte finished glass.

Separate Analog & Digital Power Supplies

The power supply is one of the most crucial parts of a system and affects audio quality in a positive or negative way. In the DX300’s power supply, we have innovatively used separate analog and digital power supplies with independent power supply management systems. The analog section is powered by a dedicated battery without any interference from the other sections. This ensures that the analog section is receiving extremely clean DC.

FPGA-Master: A Dedicated Controller

In the traditional audio players, the SoC and the OS are in charge of many tasks at the same time. Audio playback isn’t the main process and often doesn’t have the highest priority. The DX300 features a Field Programmable Gate Array (FPGA) to eliminate the negative influence from the OS’ multi-task processes. The FPGA works between the SoC and the Digital to Analog Converter (DAC). It is dedicated to requesting data from the SoC, then sending that data to the DAC. In this application, the FPGA is working in master mode in the entire audio process using two Accusilicone Fentosecond oscillators as the clocks while synchronizing all audio clocks. The FPGA and oscillators also reduce jitter to an extremely low level, building a clean digital audio signal.

Qualcomm Snapdragon 660 chip with 6GB RAM and 128GB ROM

The Bright Star Among Audio Player SoCs

14nm 8-Core Qualcomm Snapdragon 660

The DX300 is equipped with Qualcomm Snapdragon 660 as the SoC. With the powerful performance of this 14-nanometer, 8-core processor, there is currently no other SoC in the field of digital audio players that can match it! 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.

DX300 dual battery design

Patented Dual Battery Power Supply Structure

The power system is one of the most significant parts of a music player and has a decisive influence on its 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 analog section can affect each other, which can cause distortion degrading the sound quality. The DX300 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.

DX300

Quad CS43198 DAC Chips

Utilizing 4 Cirrus Logic flagship CS43198 chips to form a DAC array, the DX300 has a total of eight DAC channels with each of the eight having Low Pass Filters. These DACs are double-paralleled to achieve fully balanced output. Dual DACs in parallel can effectively reduce the discrete distortion caused by a single DAC chip due to the manufacturing process and environmental influences, which greatly improves the sound density and performance.

DX300

Replaceable Amp Card

A replaceable amp card design provides for more variety, personalization, and enjoyment of your music. The DX300 patented amp card design provides a wide range of possibilities with future amp cards to come. Longer play time, different output ports, different circuit designs, and synergy matching can be achieved by changing to a different card.

DX300

Discrete Amp Card AMP11 Comes Standard

The default amp card, AMP11, is based on AMP8's discrete circuit and is equipped with 3.5mm single-ended, 2.5mm balanced, and 4.4mm balanced output ports. All ports can also be changed to line outputs. A ±8V power supply provides sufficient and stable energy for the amp section. The maximum output current of the transistor reaches 2.7A, which allows the AMP11 to drive IEMs and headphones that require high current with ease. The maximum voltage output of the DX300 reaches 7.1Vrms, and thanks to the independent battery power supply, the maximum output power of 32&Ohm; load is as high as 1240mW.

6.5-inch High-Resolution Screen

The DX300 adopts a 6.5-inch full-screen design with a very narrow border. The screen resolutions is 2340x1080 pixels with a quality color reproduction that makes it second-to-none in a digital audio player. There is also an indicator light on the top of the screen which signals the working status of the device at a mere glance.

5th Gen Mango OS + Android 9.0

DX300 uses a Linux-based operating system specially developed for music playback, the 5th generation Mango OS. With Qualcomm 660's powerful GPU acceleration, the smoothness of operation has caught up with the Android system. The DX300 is also equipped with the Android 9.0 OS, which is far smoother than many of today's mainstream DAPs. You can freely install most apps and enjoy online streaming.

Speedy and Carefree Wireless Experience

Bluetooth 5.0 + 5G WiFi 2x2 MIMO

With an upgraded internal antenna, the DX300 gives you great coverage. The 5G wifi adopts a 2x2 MMO antenna design, with two input and two output channels, resulting in a significant upgrade to data transmission speed and data volume. The DX300 supports Bluetooth 5.0 with an enhanced antenna that provides a stronger signal over a greater distance.

Outstanding Flagship Sound Performance

In the core measurements the DX300 continues to excel. The measured signal-to-noise ratio is 125dB, the dynamic range is 125dB, and the THD+N is -113dB. These measurements lay the foundation for the flagship sound. The maximum voltage of the DX300 balanced output is 7.1Vrms, and it effortlessly drives most full-size headphones. The output power with 32&Ohm; load reaches 1240mW, a very high score among portable DAPs.
