PROJECT HEAD BOX RS BLACK

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 ohm to achieve better impedance 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 outstanding reproduction of detail, dynamics and imaging with any dynamic headphone!
