Fully Balanced THX AAA Amp Module-AM3D

THX Certified | THXAAA-78 technology | 3.5mm SE + 4.4mm Balanced

World's first THX Certified amp module

The AM3D is the world's first THX Certified standalone amp module, and also the first to contain the innovative THX AAA technology. THX AAA amplifiers, given the same power supply, have superior audio performance and output power than other competing amplifiers - allowing you to enjoy incredibly low-distortion, true audiophile-grade sound wherever and whenever. 

Fully balanced amp with 2 THX AAA-78 chips

The AM3D amp module is based around the THXAAA-78 amplifier, with both 3.5mm single-ended and 4.4mm balanced outputs. Some notable features include:

  • Dual THX AAA-78 amp chips are used for a fully balanced amplifier design
  • THX's patented feed-forward error connection topology leads to extremely low distortion and crosstalk, for a more realistic and immersive listening experience.

0.5% high precision thin film resistors | 8-stage amplification 4-way independent power supply | 2-layer isolated PCB design

The other components of the amplifier around the THX AAA amp chip were carefully chosen to not only achieve strong power output, but also ensure an exceptionally clean sound. 

Exquisite craftsmanship and design

The AM3D's shell is precisely machined by CNC and undergoes a strictly controlled color anodising process-creating a seamless blend between amo module and the FiiO player's main body minimising any color differences. 

Give your FiiO compatible products a new hurts of life

Pair the AM3D with the FiiO X7/X7 Mark II/Q5/Q5s and experience unrivalled sound. 

AM3D vs AM3B
