Description

Full Synchronization Technology
PLL+TCXO
Low-temperature drift, low-frequency drift, ultra-low phase noise, frequency stability is lower than 1ppm. With the full synchronized clock, the distortion is even lower, and sound reproduction is more realistic.

Full Balanced Output
A differential operation amplifier is used on each channel with a fully balanced output design.
2.5mm balanced, with true mirrored architecture the distortion and crosstalk are lowered.

The New Mango OS
The new Mango OS is still based on Linux, but it has been greatly minimized, optimized, and dedicated to playing music. The GPU has been implemented for the UI to lower the CPU burden. With the Open GL real-time rendering, the UI response has been greatly improved.
The DX120 uses DMA to process background I/O tasks. This frees up the CPU and allows the CPU to work better and more efficiently for decoding. This also enhances the response speed of the entire audio path increasing real-time functions allowing for close to instant real-time. The use of the DMA lowers the processing burden of the CPU.

The Lowest Distortion AK4495 Player
The DX120 development focused on obtaining the most out of the AK4495 DAC chip. The specifications for the AK4495 show a THD+N of -105dB. In real practice obtaining this THD+N can be very difficult. However our engineers, through hard work utilizing intelligent design and research, have reached a THD+N of -111dB!

The Former Flagship DAC AK4495
THD+N: -105dB (Analog Block Power Supply 7V) DR, S/N: 123dB (Mono mode: 126dB）5.6MHz DSD Input Support

XMOS XU208 USB Receiver
With Thesycon driver, a full function USB DAC.

TI BQ25890 MaxCharge
Support for Qualcomm &MTK PE+ dual quick charge.

Dual Quick Charge & USB Type-C Port
The DX120 has both the QC2.0 and the MTK-PE quick charge solutions. This supports 12V, 9V /1.5A quick charge and compatible with 5V USB charging. A full charge takes only 2 hours with a quick charge.
