Ultimate high end headphone sound!

Head Box RS is a reference quality headphone

amplier with fully balanced tube input stage (double

triode tube 6922) and single ended, class A „FET (Field

Eect Transistor)“ output stage. It oers balanced and

unbalanced input as well as balanced and un-balanced

by-pass 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 impedance matching between ampli-

er and headphones. Some experiments with dierent

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 dierent output voltages is used to

achieve the best possible S/N ratio for out-standing repro-

duction of detail, dynamics and imaging with any dynamic

headphone!
