With the D9, Audiolab continues its tradition of outstanding digital-to-analog converters – at a reference level. Building on the successes of the M-DAC and M-DAC+, the D9 marks the entry into a new performance class. With state-of-the-art converter technology, practical operation, and a wide range of professional connections, it combines technical highlights with audiophile musicality.
At the heart of the D9 is the ESS Sabre32 ES9038PRO – a top-class DAC with 32-bit resolution, extremely low distortion, and an outstanding signal-to-noise ratio. In combination with HyperStream II architecture and Time Domain Jitter Eliminator, the D9 guarantees precise, noise-free signal processing with impressive spatiality, dynamics, and detail resolution.
High-resolution audio & full MQA decoding
The D9 processes PCM up to 768 kHz / 32 bit and DSD up to DSD512 (22.5 MHz) via the USB-B input. Additionally, it is a full MQA decoder – the three-stage unfolding is carried out entirely within the device. This provides the D9 with maximum fidelity for MQA content from streaming services or local files.
Diverse connection options including AES/EBU
With 2 × coaxial and 2 × optical digital inputs, USB-B, USB-A for storage devices, AES/EBU (XLR) and Bluetooth 5.1 (aptX, aptX HD, LDAC), the D9 offers maximum flexibility. Output can be via RCA, XLR, optical, or coaxial. Additionally, 2 × 12V triggers are available for system integration. USB-A supports formats up to 96 kHz.
Individually adjustable filters & upsampling
Five digital filters and optional upsampling to 352.8 or 384 kHz allow for precise sound tuning to the source, recording, and system. This ensures even the finest details are optimally audible.
Sophisticated headphone playback
The integrated headphone amplifier with current-feedback circuitry offers high performance, a wide frequency range, and control over various headphones. Thanks to its high slew rate, the D9 also performs at a top level in the head-fi sector.
Operation via color display & remote control
A 2.8-inch IPS color display (480 × 640 px) clearly shows all information – including filter selection, source, file format, and metadata during USB-HDD or Bluetooth playback. The intuitive menu navigation is multi-lingual, and all settings can be made directly or via the remote control. The aluminum casing ensures stability and optimal shielding.
