The VISION THR-1 headphone amplifier can drive literally any headphones, but can also be used as a preamplifier. It has an RMS output power of 2.2 W (300Ω), 1.3 W (600Ω). Output connectors include two Neutrik 6.3 mm Jack sockets for low and high impedance headphones, and a symmetrical 4-pin Neutrik XLR socket for use with symmetrical headphones.
The manufacturer recommends using a custom power cable instead of the standard one included in the box.
