FPGA-Master + Dual Femtosecond NDK Oscillators
Flagship Technology Decentralization

The DX170 utilizes the FPGA-Master technology developed by iBasso. 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 al audio clocks at the same time utilizing two NDK femtosecond oscillators to achieve a fully synchronized single clock source. The FPGA and NDK oscillators also reduce jitter to an extremely low level, building a clean digital audio signal.

CIRRUS CS43131 X 2
Extraordinary Performance

Dual Cirrus Logic flagship DAC chips, CS43131, are utilized. The chip dynamic range is 130dB and a THD+N -115dB, as established by CS. With an exclusive OPAMP+BUF amplification after the CS43131,the DX170 brings forth the powerful strengths of CS43131, Regardless if using the 3.5mm single-ended or 4.4mm balanced output, with diligent tuning and adjustment, the DX170 not only retains the transparency and exquisiteness of CS43131, but also enhances the musicality and realism of the music,

The New Generation RK SOC Score of Performance is Doubled

With the advanced process technology of theRK3566, the system response is significantly improved. The AnTuTu score now reaches 100,000, far exceeding the Qualcomm 430/425 platform commonly used by players of the same price range. The user experience is greatly improved and enhanced.

Sharp 1080P Full Screen
With a Large Well Saturated Image and Excellent Contrast

16.7 million colors, 445ppi retina display, 480cd/m2 screen brightness, On Cell capacitive touch screen, 2.5D Corning glass panel, 95% light transmission and sRGB color gamut.

Android 11 OS
System Wide SRC Bypassed

The Android 11 system is debuted in the mid-range player, with amore smooth and intuitive user interface. Users are able to install APK freely and enjoy the convenience of online streaming.

The DX170 inherits the system architecture of iBasso players, enjoying a system wide, "Non-SRC" Android 11 OS.
