Audiobyte Super VOX
Multibit DSD D/A converter
For the SuperVOX, we integrated the most powerful FPGA (Field-Programmable Gate Array) we have ever used in an Audiobyte device, developing proprietary hardware defining code alongside a dual cluster of high-performance switches. What we engineered is a device that surpasses the sonic limitations of commercially available conversion chips, without resorting to very expensive ladder solutions to achieve an extraordinary level of immersion and realism in sound reproduction.
A core technology that sets the SuperVOX apart is the unique Intersymbol Interference Mitigation techniques and custom hardware perfected after thousands of hours of testing. DACs rely on reconstruction filters (low-pass filters) to smooth the output, creating a continuous analog waveform from discrete digital samples. However, imperfections in the filtering or timing mismatches can cause previous samples to "leak" into subsequent samples, creating intersymbol interference. The effects are a form of distortion that reduces the accuracy of the analog signal relative to the original digital data. To counter this and maintain a very high precision and exceptional audio fidelity, we use what appear to be ladders, but are, in fact, high-performance arrays of equal valued elements. The capabilities of this innovative design allow us, among other, to achieve impeccably low noise floors without relying on aggressive filters, preserving the natural dynamics and depth of the music.
AUDIOBYTE Super Box - MULTIBIT DSD D/A CONVERTER
The SuperVOX is Audiobyte’s most advanced DAC, powered by a custom FPGA architecture and dual high-performance switches that surpass the limitations of conventional conversion chips without relying on costly ladder designs. Its standout innovation is proprietary Intersymbol Interference Mitigation, developed through extensive testing, which preserves signal accuracy and ensures exceptionally low noise without aggressive filtering. The device employs balanced architecture, high-end clocking for jitter-free playback, and a transparent discrete output stage. Encased in a precision CNC-machined aluminum chassis, the SuperVOX combines cutting-edge engineering, luxury design, and remarkable affordability, delivering immersive, high-fidelity sound that bridges desktop and high-end audio performance.

AUDIOBYTE
THINKING IN DIGITAL
Empowering Sound, Elevating Senses
AUDIOBYTE is a sister brand of Rockna Electronics, a manufacturer of high-quality audio equipment since 1999. While Rockna Electronics is set to pursue elite levels of performance with no compromise, the mission of Audiobyte is to close the gap between computer and high-end audio. In 2023, AUDIOBYTE became an independent company, with a completely new, state of the art production facility.
Years of extensive research and development resulted in some of the most refined technologies for an inspiring and insightful audio reproduction experience. In the Audiobyte line-up we implemented features that have been reserved, until now, only for the most extravagant audio hardware. Many solutions were built from scratch to offer a package that has little or no competition at these price levels.
Each piece we ship is made to order, hand built and individually tested. In 2019 we moved to a new research and production facility that expands our manufacturing capabilities and enhances our control over the most minute details and ensure we stay true to our commitment.
