Highend headphone amplifier
Ultimate high-end headphone sound!
Head Box RS is a reference class headphone amplifier with fully balanced tube input stage (double triode 6922) and unbalanced Class A "FET (field effect transistor)" output stage. It has one balanced and one unbalanced input with looped outputs for use with other components.
The volume control consists of a high-precision controller for highest channel equality of the left and right channel.
A special impedance selector switch allows you to set the output impedance in 3 levels (5, 20 and 50 ohms) to allow the best possible match between the amplifier and the headphones. We recommend listening with different switch positions to determine the best sound for your headphones.
An elaborate multistage power supply with four different output voltages guarantees the best possible signal-to-noise ratio and the most accurate reproduction of details, dynamics and sound stage with every dynamic headphone!
