FiiO Feiao X7 Player AM3 Balanced Ear Module and AM5 High Power Ear Module Disassembled Atlas

Feiao FiiO's X7 player has been updated. These two latest earpiece modules are more inclined to high-power output. They are AM3 balanced output earpiece module and AM5 high-power earpiece module respectively. The previously introduced AM2 is positioned as a medium power module. Taking 16 ohm impedance as an example, the official data AM2 can provide 350mW output, while the balanced output of AM3 is 420mW/250mW [balanced/unbalanced], and the AM5 high-power module can reach 500mW output power. The AM3 balanced ear module is priced at 698 yuan, while the AM5 high-power ear module is priced at 598 yuan.

AM3 balanced ear module is connected to the analog signal from X7, it directly uses one OPA1622 for each channel to do balanced voltage amplification, and then one OPA1622 for each channel to do current buffer amplification for earphone output. AM3 also provides a set of standard unbalanced outputs, which are also converted from balanced outputs by two OPA1622 op amps.

and AM5 high-power earphones can't accidentally use this IC of the TPA6120A to expand the current of earphones. We recently heard that the output level of earphones using TPA6120A products is much better than a few years ago. It seems that everyone has touched the design doorway? The AM5 voltage amplification part uses JRC's MUSE02. This chip is expensive and has a good index, but the reputation of timbre and our experience show that there is no special finished product at present.

Since there are not many disassembled pictures, they will be published in this article. But the evaluation report is still divided into two. On July 13, Soomal released the evaluation of Feiao AM3 balanced earpiece module. On July 18, the evaluation of Feiao AM5 high-power earpiece module was released.
