Austrian Audio Full Score One Premium Headphone Amplifier

The Austrian Audio Full Score One is a high-performance headphone amplifier designed with a focus on transparent audio reproduction and exceptional handling of both low and high-impedance headphones (from 10 Ohms to over 300 Ohms).

Its innovative design ensures low Total Harmonic Distortion (THD) across all output levels, providing a clear, distortion-free listening experience. The amplifier’s advanced circuit design, including a fully symmetrical voltage feedback circuit and cascoded input stages, sets it apart from typical headphone amps, focusing on reducing noise and improving time-domain accuracy.

Handles a Wide Range of Headphones

Full Score One is designed to work with a wide variety of headphones, from low-impedance models as low as 10 Ohms to high-impedance headphones of over 300 Ohms. This means you can pair it with practically any high-end headphone, ensuring optimal performance regardless of the headphone type.

Innovative Circuit Design for Low Distortion

The amplifier uses a symmetrical voltage feedback circuit and a high-speed complementary push-pull gain stage, keeping Total Harmonic Distortion (THD) at ultra-low levels across all output ranges. This means you get crystal clear sound with minimal distortion, ensuring accurate audio reproduction.

Optimised Time-Domain Performance

While many amplifiers focus purely on frequency response and THD, the Full Score One emphasises performance in the time domain. It achieves exceptional slew rate and rise time, meaning it can handle fast signal changes more cleanly, avoiding phase issues and delivering a more precise sound, particularly with transient-heavy audio.

Efficient Power Use

The triple emitter follower output stage operates in Class B, making the Full Score One energy-efficient while still delivering powerful and detailed audio. It strikes the perfect balance between energy savings and sound quality, which is especially important for longer listening sessions.

No Gain Switch – Low Noise Design

Instead of using a gain switch, the Full Score One uses a low-noise design that can amplify both high-sensitivity and low-sensitivity headphones without introducing unwanted noise. This makes it particularly useful for listeners who demand silent operation even when using sensitive headphones.

Customised Volume Control

The amp includes a specially designed ALPS RK271 potentiometer with a custom taper curve, allowing for smoother and more precise volume control. Whether you're making subtle volume adjustments or cranking it up, the Full Score One provides accurate control with no volume jumps, even with high-sensitivity headphones.
