Innovative Design
The Full Score One headphone amplifier stands out for its original and functional design. Its metal body encloses a knob, which also functions as the front panel edge , the 6.3mm outputs, the 4-pin XLR hidden by a cover , and the buttons for power and activation of Austrian Audio's "True Transient Technology" .

True Transient Technology for Exceptional Performance
At the heart of Full Score One is True Transient technology, exclusive to Austrian Audio. This feature ensures lightning-fast energy delivery even for the steepest transients , guaranteeing flawless audio performance. The option to deactivate this technology allows for adaptation to various audio productions.

Versatility and Breadth of Use
The Full Score One is designed as a low-noise power amplifier , capable of handling headphones with various impedances and sensitivities. Featuring a fully symmetrical, broadband voltage feedback circuit, it offers minimal THD reduction at any output level and frequency range , ensuring a detailed sound experience even with less sensitive headphones.

Optimized Volume Control
The volume control, with a custom curve, ensures adequate adjustment even at low levels without the need for a gain switch . A high-speed, high-impedance JFET amplifier precedes the volume control to keep the capacitive load on the source as low as possible and ensure maximum immunity to radio frequency interference.

Powerful Linear Power Supply
Equipped with a robust linear power supply , Full Score One is designed to seamlessly handle more than one pair of headphones connected simultaneously . The audio performance is astonishing, offering a superior listening experience with any type of headphones, both high and low impedance.

Universal and Incredibly High-Performance
With its ability to accommodate a wide range of headphones and deliver exceptional audio performance, Full Score One presents itself as the universal headphone amplifier . Its presence is almost imperceptible, ensuring a high-quality listening experience regardless of how difficult it is to drive the headphones.
