The FiiO AM2A is an official version of the popularly modified AM1 amp for the modular X7 DAP and the upcoming Q5 DAC. While it uses a similar amplifier chip set as the AM1, it merges it with the same voltage supply as the AM2. As it can power the same range of headphones as the AM2 but with a different sound signature, it has been classed the AM2A. This module is great for popular styles of music as it presents a smooth and neutral resolution. It presents textured mids, clear highs and rich lows to bring out the best from your popular genres.

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 AM2 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.
