• While most of Allnic's product line had a significant price increase in 2021, this unit had a price drop and maintains the same quality throughout!


    The HPA-3000 GT is Allnic Audio’s output transformer coupled, stereo headphone amplifier. The HPA-3000 GT has a voltage gain of +28dB, and a maximum output of three (3) watts. It works best with headphones having an impedance of from 30 to 600 ohms.


    Key Features

    The HPA-3000 GT has the following features:

    • Works best with headphones having an impedance of from 30 to 600 ohms
    • High-quality, NOS tubes
    • Pure Class A operation
    • Headphone output: The HPA-3000 GT is equipped with two (2) headphone output ‘jacks’ and two (2) four (4) pin XLR All work for both low and high impedance headphones
    • Pre-amp output: The HPA-3000 GT is equipped with one (1) pair of RCA pre-amp outputs, whose impedance is around 10 ohms; this extremely low value provides very powerful driving capability with the widest frequency range to a connected amplifier
    • Volume control: The HPA-3000 GT’s volume control is the large knob in the center of front panel. It rotates clockwise (gain increased) and counter-clockwise (gain reduced) – No remote control
    • As are all Allnic Audio products, the HPA-3000 GT is fully RoHS (EU Reduction of Hazardous Substances regulation) compliant in construction and materials
