Product Description

FiiO AM5 High Power Amplifier Module is a replaceable upgraded amplifier unit that can be added and used with your FiiO X7 to further enhance the sound quality. Also available for use with the X7 is the Medium Power AM2 or Balanced Power AM3 models.


The AM5 uses the MUSES02 by MUSES - the audiophile semiconductor division of the New Janpan Radio Co. Ltd. - for voltage amplification like the AM2. With the TPA6120A2 - a current feedback differential input high fidelity headphone amplifier integrated circuit usually applied on desktop device by Texas Instruments as the headphone amplifier chip to achieve lower distortion, higher bandwidth and a higher slew rate. In combination with our setup, it effectively lowers the output impedance of TPA6120A2 so as to lower the amp output impedance to the maximum level. The FiiO AM5 headphone Amplifier module is capable of ultra-high current for highly-dynamic musical performance and hardware-level adjustable gain to cater to different headphones.


Replacing the modules is extremely easy; simply using the Screwdriver that came with your X7 it is merely a matter of undoing 2 screws to remover the AM1 and replace it with the AM5. Although protection circuits are installed on the X7, it is still recommended to perform the module exchange when the X7 is turned off. The FiiO AM5 unit comes in a metal protective box which will protect which ever amp you choose to store in there.
