Austrian Audio Full Score one

High-end headphone amplifier – Made in Austria

The Full Score one is a no-compromise, universal headphone amplifier built exclusively with high-end or military-spec components. Its proprietary True Transient Technology (TTT) delivers lightning-fast transients and uncolored detail—remaining composed even during the most demanding musical passages.

The circuit is fully discrete, with no integrated ICs in the signal path. A high-end volume control with a specially tuned curve enables precise, comfortable adjustment even at low listening levels—without any gain switch. Before the volume control, a high-speed, high-input-impedance JFET buffer minimizes capacitive loading on the source and suppresses RF interference.

Designed to behave like a low-noise power amp, it drives low-impedance headphones from 10 Ω all the way up to 600 Ω with ease—even for insensitive models.

Design & Features

The compact metal chassis has a distinctive layout: a large volume knob at the right edge of the front panel, two 6.35 mm outputs, a hidden 4-pin XLR behind a flap, plus the power and TTT switches. With one press, TTT injects instant energy for even the steepest transients—yet can be disabled for older recordings if preferred.

Circuit Topology

A wideband, fully balanced voltage-feedback design with a triple emitter follower Class-B output stage, a fast complementary push-pull amplifier, and a parallel differential cascode input keeps THD extremely low across the entire frequency range, preserving the finest nuances.

Connections

• Inputs: 2 × XLR, 2 × RCA (parallel)
• Outputs: 2 × 6.35 mm, 1 × 4-pin XLR

Conclusion: The Full Score one is so neutral and effortless it virtually disappears—regardless of whether you use easy-to-drive or demanding headphones.
