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!
