FiiO JadeAudio GIGAS 1 Desktop Headphone Amplifier, 4600mW High-Power Balanced Output, Class AB Discrete Circuit, 4.4mm & 3.5mm Amp for Planar & High-Impedance Headphones (Black)

About this item

The GIGAS 1 is a compact desktop headphone amp from FiiO's JadeAudio line, built on a discrete Class AB circuit for a warm, controlled sound. It pushes up to 4600mW per channel through its balanced 4.4mm output, with a 3.5mm single-ended output alongside it that also supports CTIA mic pass-through. Flexible RCA and 3.5mm inputs plus dual gain modes let it pair with sources ranging from smartphones to CD players, and USB-C input supports both 5V and PD 12V power for extra headroom when you need it.

• Class AB discrete amp stage built with ON Semiconductor MJE243G/MJE253G transistors for a smooth, natural sound
• Up to 4600mW per channel from the 4.4mm balanced output at 32Ω — enough power for planar and high-impedance headphones
• Both 4.4mm balanced and 3.5mm single-ended outputs; the 3.5mm also passes through CTIA mic signal for headsets and calls
• RCA and 3.5mm inputs work with DACs, phones, computers, CD players and more, with dual gain settings for IEMs to full-size cans
• USB-C powers it two ways: standard 5V or PD 12V, with PD mode giving extra headroom and dynamics
