Mesmerizing listening pleasure

The Full Score one is Austrian Audio’s debut headphone amplifier, applying the same meticulous approach to its design as with its family of award-winning headphones and microphones. Created with both home listeners and high-end mixing and mastering engineers in mind, the Full Score one takes headphone performance to new levels, revealing a new world of listening pleasure and precision to all users, from those unfamiliar with the world of premium audio to the already committed audiophile.

Beautifully built and employing only high-end and military-grade components, the Full Score one looks as assured as it sounds. Integrate the Full Score one into a sound system, pair it with capable headphones, and you revel in fast and accurate performance.

TTT - True Transient Technology

The new model features Austrian Audio’s proprietary True Transient Technology (TTT), which helps deliver the most jaw-dropping transients, such as the snap of a kickdrum or the delicate pluck of a guitar string in unaltered detail. The analogue amplifier design is as clean as a whistle: Fully discrete, no ICs in the signal path, and low noise. Lovely. All made in Austria and built to last. Our technical approach to our first headphone amp was comparable to building a very low-noise power amplifier. The Full Score one handles low-impedance headphones down to 10 Ohms as well as high-impedance, low-sensitivity headphones with over 300 Ohms. Thanks to innovative design – the amplifier comprises a wide band, fully symmetrical voltage feedback circuit with a triple emitter follower output stage biased in class B, a high-speed complementary push-pull gain stage and a cascoded parallel differential input stage – the Full Score one secures very low THD (Total Harmonic Distortion) at every output level and over a wide frequency range. This makes the Austrian Audio Full Score one a perfect duo together with the Austrian Audio The Composer.
