Audiobyte — DAC

SUPER VOX

A breakthrough multibit DSD DAC engineered for absolute emotional realism.

The Super Vox represents the pinnacle of Audiobyte's research into digital-to-analogue conversion. By abandoning the limitations of off-the-shelf conversion chips in favour of a fully bespoke FPGA-based architecture, it achieves a level of tonal purity and micro-dynamic precision that redefines digital playback. At its core lies a powerful AMD 7-series Artix FPGA running proprietary algorithms that define a unique multi-level delta-sigma modulator. This system employs high-performance arrays of equal-valued elements, which allows the DAC to bypass aggressive digital filtering. The result is a sound that remains entirely faithful to the original recording, preserving the natural flow and harmonic depth of the music without introducing artificial artefacts. Designed as the definitive digital heart of the Super Series, the Super Vox is intended for the discerning listener who views the human voice as the ultimate test of fidelity. It is a device built with an obsession for signal integrity, housing its sophisticated circuitry in a precision-machined aluminium chassis that ensures mechanical stability and long-term acoustic performance.

Design & Philosophy

The Super Vox was developed with a single goal: to transcend the sonic limitations of commercially available conversion chips. Audiobyte engineers spent thousands of hours perfecting unique intersymbol interference mitigation techniques, ensuring that the reconstruction filter does not compromise the natural dynamics of the music. By focusing on arrays of equal-valued elements rather than traditional ladder designs, the unit achieves extraordinary linearity and a noise floor that remains strikingly low even during the most complex passages.

Build & Materials

Consistent with the Super Series aesthetic, the Super Vox is housed in a chassis CNC-machined from a solid block of premium aluminium. The bead-blasted and anodised finish provides a luxurious, durable surface that is resistant to fingerprints and marks. Internally, the design prioritises electrical isolation with a low-noise linear power supply and high-quality silver-plated copper cabling, reflecting an obsession for quality in every internal connection.

Sonic Signature

The Super Vox delivers a presentation that is tonally present, emotionally expressive, and remarkably dimensioned. It has been deliberately voiced to render the human voice with authentic body and texture, making it an ideal reference for vocal-heavy recordings. By removing the veil of digital fatigue, the DAC allows for an immersive listening experience that bridges the gap between the clinical accuracy of digital audio and the natural, fluid engagement of live performance.
