• Fully balanced double mono design • Tube input stage • Class-A FET output stage • Switchable output impedance for ultimate performance • Superior low distortion • Low noise components for ultimate dynamic & detail • Output: 6,3mm socket • Full metal casing in silver or black • Optional Upgrade: Linear power supply Power Box RS Uni 1 (or 4) for further improved sound quality 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 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 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!
SRP: € 799,00 Recommended accessoires:
The addition of linear power supply Power Box RS Uni 1-way (SRP € 399,00) or Power Box RS Uni 4-way
CAUTION: Please check the power connection of your Head Box RS on the rear side. In case of an 18V 2.5 connection, a Connect It Power MiniXLR 18V 2.5 adapter cable is necessary to power the unit with a Power Box!
