HIFIMAN GA-10 Tube Headphone Amplifier

World-Renowned Tubes

The vacuum tubes used in the GA-10 amplifier include (4x) ECC83/12AX7 and (4x) EL84 which are found in select high-fidelity amplifiers.

The EL84 vacuum tubes are featured in leading guitar amplifiers used by some of the most successful professional musicians, adding an element of natural analog warmth to the sound output.

Clean Power

The power supply features a specially designed, shielded 120W transformer combined with an independent, low-noise voltage amplifier, stage voltage regulator circuits for the left and right channels, and a low-noise negative voltage regulator circuit to produce exceptional clarity and all-around superior sonics.

The GA-10 features an audio output of 3 watts per channel at 300Ω, making it a great match for most available high-impedance headphones. The GA-10 is also equipped to drive high-efficiency low-impedance headphones.

The delicate SEPP architecture combined with superior components and vacuum tubes provide a clear, quiet sound that is both vibrant and powerful at an incredible value.

Design

The design goal of the GA-10 is to achieve the delicate, clear sound unique to high-end tube amplifiers. While its nominal power output may not be high, its controllability is extraordinary. The GA-10 performs exceptionally well whether listening to a complex symphony or classic rock band. It is truly an audiophile-grade amplifier.
