Austrian Audio Full Score one

The Austrian Audio Full Score one is Austrian Audio's debut headphone amplifier, a fully discrete, no-IC solid-state design with True Transient Technology (TTT), designed specifically to unlock the performance of demanding headphones from 10 to 600 ohms. The designed amplifier partner for the Austrian Audio Composer. Engineered and manufactured in Vienna, Austria.

Type and Technology

Fully discrete solid-state headphone amplifier, no ICs in the signal path. Austrian Audio's proprietary True Transient Technology (TTT), a circuit topology that prioritizes transient accuracy and speed. Fully symmetrical voltage feedback circuit: cascoded parallel differential input stage, high-speed complementary push-pull gain stage, triple emitter follower output biased in Class B. 10 to 600 ohm headphone range. Maximum output voltage: 19dBV (9Vrms) at 0.01% THD. THD+N at 10 ohms at 1W: 0.0005%. Self-noise: 1.5µVrms. Slew rate: 200V/µs. Power bandwidth: 5Hz to 2MHz. Inputs: 2x XLR balanced, 2x RCA (parallel). Outputs: 2x 6.35mm single-ended, 1x 4-pin XLR balanced. Military-grade components throughout. Made in Austria.

Sound Character

Fast, precise, and revealing, transient accuracy and very low distortion across all frequencies. The 0.0005% THD at 1W into 10 ohms demonstrates its control over low-impedance headphones. Transparent to source material, revealing what the headphone and recording are genuinely capable of.

Best For

Audiophiles and engineers who want a reference solid-state headphone amplifier with exceptional transient accuracy and ultra-low distortion, the designed partner for the Austrian Audio Composer, and compatible with any headphone from 10 to 600 ohms.
