Fiio GIGAS 1 Desktop Headphone Amplifier (4600mW Balanced)

Fiio GIGAS 1 Desktop Headphone Amplifier (4600mW Balanced)

The GIGAS Series takes its name from the Greek word “GIGAS” — meaning “giant” — a fitting symbol for its extraordinary output power. Developed alongside the JT7 planar headphones, this series was created to solve a real-world challenge: low-sensitivity planar headphones require significant power, while sources capable of driving them properly are often expensive. The GIGAS 1 delivers this power at an accessible price, allowing users to unlock the full potential of entry-level full-size planar headphones from FiiO and beyond.

Class AB Discrete Transistor Amplification

At the heart of the device is a carefully engineered discrete amplification circuit based on an op-amp + transistor current amplification topology. The classic onsemi MJE243G/253G transistor pair provides high current capability and low output impedance, delivering an impressive 4600 mW + 4600 mW balanced output power.

The result is a smooth, natural, and musical sound capable of effortlessly driving both full-size headphones and IEMs.

Dual Headphone Outputs

Both the 3.5 mm single-ended output and the 4.4 mm balanced output offer broad compatibility with different types of headphones.

The 3.5 mm output also supports CTIA-compatible microphone signal passthrough, making it ideal for gaming voice chat, phone calls, and multimedia applications.

Dual Inputs

Equipped with 3.5 mm and RCA inputs to ensure wide compatibility with various audio sources.

You can easily connect digital audio players, smartphones, computers, or CD players, providing a stable connection for Hi-Fi listening or desktop entertainment, with no limitations on the audio sources you can use.
