HIFIMAN GA-10 (Like New) Tube Headphone Amplifier

Like new, open box, no signs of use, full warranty, complete packaging

The HIFIMAN GA-10 is the Goldenwave 10th Anniversary tube headphone amplifier – a fully analogue design built around eight vacuum tubes in a SEPP (single-ended push-pull) circuit with direct tube output. It delivers warm, sweet and detailed sound with powerful dynamics and solid bass, and has enough power for demanding high-impedance headphones as well as efficient planar headphones such as the HIFIMAN HE1000 series.

Key Features

• Tube headphone amplifier with SEPP (single-ended push-pull) circuit and direct tube output
• 4 × ECC83/12AX7 tubes in the preamplifier stage and 4 × EL84/6P14 tubes in the power stage
• Specially designed, shielded 120 W linear transformer
• Output power up to 3000 mW at 300 ohms and 600 mW at 32 ohms
• Impedance switch (LOW / HIGH) for the best match with low- and high-impedance headphones
• Three headphone outputs: 4-pin XLR balanced, 4.4 mm balanced and 6.35 mm single-ended
• Balanced XLR and single-ended RCA analogue inputs with input selector
• ALPS carbon film volume potentiometer
• THD+N only 0.001%

Tubes for natural analogue warmth

The GA-10 uses renowned ECC83/12AX7 and EL84 tubes, found in high-end hi-fi amplifiers and in legendary guitar amplifiers used by top professional musicians. Together with the SEPP circuit they create a crisp, detailed sound with a delicate touch of natural analogue warmth, while keeping noise and distortion extremely low.

Power for any headphones

The specially designed, shielded 120 W transformer gives the GA-10 a large power reserve for dynamic, controlled bass. With 3 W per channel at 300 ohms it is an ideal partner for most high-impedance headphones, while the impedance switch and 600 mW at 32 ohms make it equally suitable for low-impedance, high-efficiency planar magnetic headphones.

Flexible connectivity

On the back, balanced XLR and single-ended RCA inputs connect to your DAC or preamplifier. On the front, a 4-pin XLR balanced, a 4.4 mm balanced and a 6.35 mm single-ended output let you use almost any headphone without adapters.
