Enjoy powerful, pure headphone amplification with the FiiO GIGAS1, designed to maximise performance without complications. Features FiiO GIGAS1 amplifier Pure analogue amplification: With no DAC or digital features, GIGAS1 focuses on a clean, stable signal, ideal for users with an external DAC or portable player. Class AB architecture with discrete transistors: ON Semiconductor MJE243G and MJE253G components deliver dynamic sound with powerful bass and detail throughout the frequency range. High power up to 4.6 W RMS: Drives everything from IEMs to demanding planar headphones, ensuring control and authority even at high impedance. Two headphone outputs: Balanced 4.4 mm output for maximum power and separation, plus a conventional 3.5 mm output compatible with CTIA microphones. Versatile analogue inputs: Easily connect desktop DACs, portable players or streamers via RCA or a 3.5 mm jack, keeping the signal entirely analogue. USB-C power with Power Delivery: Supports up to 12 V for powerful output without bulky external power supplies, making desktop installation easy. Compact, robust design: The metal chassis dissipates heat efficiently, with essential front controls for intuitive, distraction-free operation. Includes USB cable and quick-start guide: The device includes everything needed for immediate use, avoiding additional accessory purchases. The FiiO GIGAS1 is ideal for users seeking powerful, straightforward analogue amplification without unnecessary extras. It complements high-quality audio sources and brings out the best in your favourite headphones.

It supports dynamic and planar headphones with impedance between 8 and 350 Ω, from IEMs to high-end models requiring substantial power. Do I need an external DAC to use this amplifier? Yes. GIGAS1 has no DAC; it is designed for sources that already convert digital audio to analogue, such as DACs or portable players with a line output. What advantages does the balanced 4.4 mm output offer? It provides greater power and better channel separation, ideal for headphones supporting balanced connections and a cleaner, more powerful sound. How is the amplifier powered, and what are the benefits? It uses USB-C with Power Delivery support up to 12 V, allowing easy installation without bulky external power supplies. Suitable for you if: You want powerful, uncomplicated analogue amplification. You have an external DAC or a player with a line output. You want to drive high-impedance or planar headphones. You prefer a compact, robust desktop design. Not suitable for you if: You need an amplifier with a built-in DAC or digital features. You want wireless connectivity or advanced menus. You only use very sensitive headphones that do not need high power. You prefer a portable amplifier with an internal battery.
