*Please check with our online customer service team for stock availability Genuine
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 THX AAA-78 amplifier, with both 3.5 mm single-ended and 4.4 mm balanced outputs some notable features.

THX's patented feed-forward error correction 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 chose to not only achieve strong power output, but to 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 anodizing process - creating a seamless blend between amp module and the FiiO players's main body by minimizing any color differences.

Pair the AM3D with the FiiO X7, X7 Mark II, Q5, or Q5S and experience unrivaled sound.
