The FiiO AM3 is the fifth interchangeable module made available for the modular X7 DAP and the upcoming Q5 DAC. By using this module youare able to access the phenomenal audio precision of the FiiO X7 through balanced headphones, thereby giving you an incredibly clear listening experience. The AM3 uses 6 brand new OPA1622 amp chips from Texas Instruments to achieve full channel balanced output for both 2.5mm TRRS balanced output and 3.5mm single-end output. These chips also help achieve an ultralow THD + N of –119.2 dB (0.000018%) while driving a 32Ω load at 10 mW output. With an output power of 150 (before clipping occurs), this is the best module for high power, interference-free audio from your X7.

Changing your amp module is simply a case of unscrewing the screws towards the bottom of the X7 with the screwdriver provided in the X7s packaging. You then detach the AM1 module before replacing with the AM5 and re-attaching the screws. Make sure the X7 is powered down while doing this. If you are uncertain which is which, the name of the unit is marked on the rear side.
