FiiO Feiao X5III Portable Smart Audio Player Disassembly Atlas

Feiao FiiO released the X5 third-generation audio player in December 2016 at a price of 2498 yuan, which is basically the same as the price when the previous two generations of X5 were released. However, in terms of design, functions and even the core of the system, X5III has been fully upgraded, and there are even signs of challenging the flagship X7 player. Perhaps X5III is a small version of X7? The appearance and technology of X5III are further improved. The whole body and details are CNC machined. Both the keys and the left knob are carefully designed. It uses a 4-inch 800x480 touch screen, Android operating system, RK3188 main processor, supports 2.4GWiFi and apt-X Bluetooth coding, has 32GB of built-in storage space, and provides dual card slots, each of which can support SDXC 256G memory cards. X5III supports Qualcomm QC2.0 and MTK Pump Express Plus high-speed charging specifications.

X5III uses dual AKM AK4490 DAC chips, each DAC corresponds to one channel, each channel has one TI BB OPA1642 op amp as LPF, and TI customized OPA426 op amp as headphone expansion and amplification output. X5III itself supports 2.5mm balanced headphone output, supports Lineout and digital output, and supports USB DAC mode. The audio architecture of the system has been improved. The X5III system can support any third-party app to call the audio core system. Soomal will release the evaluation report of Feiao X5III on the 10th of the first month of the lunar calendar.
