iBasso has introduced a flagship digital music player called the DX300 that combines a compact design and still has a more advanced sound quality than previous generations. The iBasso DX300 can still use the new AMP11 module.
Inside the DX300 are 4 CS43198 DAC chips (the DX160 uses 2 CS43198 DAC chips and the DX220 uses 2 ES9028 PRO chips). Each channel will use 2 chips with 8 Low Pass Filters to get full-balanced independent decoding.
Pre-decoder uses an FPGA chip to solve problems on the Android operating system, prioritizing the audio signal stream from SoC through FPGA and then to DAC. The clock system uses 2 Accusilicone Femtosecond oscillators to provide timing signals to FPGA and DAC to reduce signal interference on the Android system. SoC chip used on the iBasso DX 300 is Snapdragon 660 with 6GB and 128GB of internal memory with Android 9 operating system.
The AMP11 amp has three audio output ports with one 3.5mm single-ended, balanced 2.5mm and 4.4mm, all adjustable to line-out. However, the DX300 portable music player will use a new, more compact amp module system and will not be compatible with previous amp modules of the DX220 series.
The power supply circuit also plays an important role, so iBasso uses an independent power separation system with 2 different batteries. One 2000mAh battery for the Analog circuit and one 4000mAh battery for all digital signals.
