Austrian Audio Full Score one
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. | |
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.
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. |
