True Transient Technology (TTT)
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.

Austrian Audio Full Score One
The Full Score One is a compact, studio-focused headphone amplifier that pairs surgical precision with muscular dynamics. Its standout trait is studio-grade clarity and dynamic punch, delivering crisp transients, tight low-frequency grip and layered stereo imaging.
As noted by What Hi‑Fi?, the True Transient Technology (TTT) button sharpens leading-edge definition and helps the amp resolve complex orchestral passages; wide bandwidth, a high slew rate and low self-noise underpin its excellent dynamics and near-silent background.
Build quality is impressive for a desktop unit — curved metal casework, neat volume integration and a discrete internal layout. With two 6.35mm outputs plus a 4-pin XLR and the ability to drive 10–600Ω loads, it’s tailored for obsessive listeners with high-quality sources who want analytical, unvarnished playback. The Full Score One is a well-made, purpose-built choice for critical headphone listening.
Pros
- Clear, detailed and balanced sonic presentation with strong imaging and low-frequency grip.
- Solid build and neat internal layout — curved metal casework and quality parts inspire confidence in longevity.
- True Transient Technology (TTT) increases leading-edge definition and detail resolution for complex material.
- Broad compatibility and drive capability (10–600 Ω) with both single-ended and balanced headphone outputs.
&
Cons
- Very limited analogue input arrangement effectively meaning a single usable input (RCA in parallel with XLR).
- Volume control has limited travel, making fine low-level adjustment tricky with very sensitive headphones.
Sound Quality
90/100
What Hi‑Fi highlights strong transient punch and the ability to deliver the verve and rhythmic drive of demanding tracks without compromising expression. The proprietary TTT circuit and measured specs (high slew rate and wide power bandwidth) support excellent dynamic authority.
Noise Floor
89/100
No reviewer reports audible hiss and the published self-noise (EIN 136 dB(A) / 1.5µVrms) and high SINAD figures indicate a very low noise floor suitable for most sensitive headphones. There is no explicit reviewer phrase like 'black background' but both specs and the lack of hiss mentions support a near-silent performance.
Headphone Compatibility
88/100
The unit is specified to drive 10–600 Ω and What Hi‑Fi notes it handles most headphone loads without issue; outputs include 2x 6.35mm and a balanced 4‑pin XLR. One caveat is limited volume control travel making very sensitive designs harder to set precisely, so while power and connectivity are excellent, fine-grain control for ultra-sensitive IEMs is slightly constrained.
Build Quality
92/100
Described as beautifully made with curved metal casework, neat volume integration and a discrete internal layout using quality parts. Reviewers note evident care in assembly; only minor gripe is that the volume dial could be thicker for easier handling.
Features Connectivity
86/100
Balanced XLR and stereo RCA inputs (parallel) plus two 6.35mm jacks and a 4‑pin XLR headphone output give strong connectivity; the proprietary True Transient Technology (TTT) is an added performance feature. No DAC or digital inputs are present, so it scores well for analog desktop use but is not a full-featured streaming/DAC hub.
Value for Money
89/100
At around $1,599 reviewers suggest it may be over‑kill for many listeners but is warmly recommended for obsessive/high‑end headphone users who will benefit from its clarity and build. The language implies a justified premium for its target audience rather than a mass-market bargain.
