FiiO CLASS A Desktop Headphone Amplifier & Preamplifier

Dedicated amplification for your favourite headphones

Build a listening setup around the music you love. The FiiO CLASS A offers a fully balanced differential architecture with up to 4,000mW per channel into 32Ω through its balanced headphone outputs.

Adjust the sound to suit your listening

Five gain settings help match the amplifier to different headphones. Independent bass and treble controls offer ±10dB adjustment, giving you hands-on control over your preferred balance.

Connect your desktop or home audio system

Choose from four analogue inputs and three headphone connections. RCA and balanced XLR line outputs allow the CLASS A to serve as a preamplifier for powered speakers or an external power amplifier. A 12V trigger input and output support coordinated power control with compatible equipment.

A substantial power supply

A custom 60W toroidal transformer and 20,000μF capacitor reservoir support the amplification circuitry. DC servo control and built-in protection circuits monitor operating conditions to help protect the amplifier and connected headphones.
