Product information "Fosi Audio GR70"
Tube headphone amplifier
- Pure tube amplification
- Adjustable impedance and bass and treble control
- 2-in-1 headphone amplifier and preamplifier
- Supports headphones with an impedance of 16-300 Ω
Vintage charm meets modern precision
The GR70 is a headphone amplifier and preamplifier in one.
Thanks to the many headphone connections and RCA inputs/outputs, you can easily integrate this tube preamplifier into your home audio system.
Pure tube amplification:
The GR70 headphone tube amplifier combines vintage charm with modern technology and delivers authentic tube sound.
It's perfect for headphone fans and pairs perfectly with over-ear and in-ear headphones for premium sound.
Quad tubes:
Features two 5654W and two 6Ж4 vacuum tubes for two-stage amplification.
The 5654W tubes increase the voltage, while the 6Ж4 tubes provide the power amplification.
This configuration ensures a balanced, transparent and structured sound.
User-friendly design:
This tube headphone amplifier features intuitive controls, including a large volume knob, dual-sided vents, bass and treble controls, and high/low impedance mode switching, making it versatile.
Two in one:
It supports low and high impedance mode switching to connect 16 Ω to 300 Ω headphones and features 6.35 mm/3.5 mm headphone jacks on the front and RCA inputs/outputs on the rear for integration into home hi-fi systems.
Compact and powerful:
Made from CNC machined aluminum alloy, the GR70 is both robust and elegant.
Despite its compact size, it delivers an output power of up to 300 mW and a 1.2 V RCA output with a signal-to-noise ratio of ≥97 dB - for a warm, clear and dynamic sound.
