Pro-Ject Head Box RS

Highend headphone amplifier

Ultimate highend headphone sound!

Head Box RS is a reference quality headphone amplifier with fully balanced tube input stage (double triode tube 6922) and single ended, class A „FET (Field Effect Transistor)“ output stage. It offers balanced and unbalanced input as well as balanced and unbalanced bypass connectors for using the pass-through input signal with other components.

Volume control consists of a precise volume regulator with matched resistance between left and right channel.

A special output impedance selector allows to adjust output impedance in three steps 5, 20 and 50 ohms to achieve better im-pedance matching between amplifier and headphones. Some experiments with different positions of output impedance selector are highly recommended to get the ultimate sound experience for your headphone.

An advanced multi-stage power supply with four different output voltages is used to achieve the best possible S/N ratio for out-standing reproduction of detail, dynamics and imaging with any dynamic headphone!
