The Best of Both Worlds: Pro-Ject Head Box RS
Headphone Amplifier Features Fully Balanced Tube Input Stage and
Single-Ended Class-A FET Output Stage
Pro-Ject Head Box RS headphone amplifier uses tube technology and a Class-A output stage to take headphone listening to deliriously good levels of enjoyment. With Head Box RS,
ear-dazzling dynamics, detail, and soundstaging are an arm's reach
away. You'll hear music come to life with pinpoint detail and spot-on
imaging all the while experiencing terrific clarity courtesy of Head Box RS' internal components and audiophile design.
Clever inventions can bring you close to the actual experience of tubes, but there's no substitute for the real thing. Pro-Ject Head Box RS
knows this well. Equipped with a fully balanced tube input stage and
single-ended Class-A FET output stage, this heady instrument makes your
'phones and music sing via its switchable output impedance, insanely low
distortion, and a precision volume control.
Balanced and Unbalanced Inputs, Plus Pass-Through Options
The Pro-Ject Head Box RS headphone amplifier combines a 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. Its volume control consists of a precise volume regulator
with matched resistance between the left and right channels.
Impedance Adjustments Allow Custom Matching to Any Headphone
A special output impedance selector allows to adjust output
impedance in three steps 5, 20, and 50 ohms to achieve better impedance
matching between amplifier and headphones. 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.
