Unitra DSH-805 DAC

Unitra, a storied name in audio engineering, has unveiled the DSH-805, a reference-class digital-to-analog converter (DAC) that sets a new standard for high-fidelity sound. Combining cutting-edge ESS SABRE® technology with Unitra’s proprietary innovations, the DSH-805 is designed to unlock the full potential of modern digital audio sources, delivering a natural, dynamic, and immersive listening experience for audiophiles and music enthusiasts.

The Heart of Sonic Excellence

At the core of the DSH-805 lies the flagship ESS SABRE® ES9039MSPRO DAC, featuring eight integrated DACs—four per channel—powered by the patented Hyperstream® IV architecture. This advanced chipset ensures absolute linearity, minimal distortion, and precise signal reproduction, preserving every detail of even the most demanding recordings. The result is a sound that remains faithful to the artist’s original intent, offering unparalleled clarity and dynamics.

The DSH-805’s analog output stage, built around 18 OPA161x operational amplifiers, further refines its sonic character. This proprietary design delivers coherence, spaciousness, and natural reverberations, blending technical precision with a rich, vibrant tone. Gold-plated RCA connectors and balanced XLR outputs ensure reliable, high-quality connections, minimizing signal loss for complete sonic transparency.

Unmatched Format Support and Flexibility

The DSH-805 supports a wide array of high-resolution audio formats, including PCM, DSD native, DoP (DSD64 via S/PDIF), and MQA. With an integrated MQA decoder and renderer, the device faithfully reproduces MQA and MQA Studio formats, while also supporting OFS streams pre-decoded by external streamers. Two DSD transmission methods—DSD native and DoP—offer versatility for audiophiles seeking the highest fidelity.

For personalized sound, the DSH-805 features seven PCM digital filters, allowing listeners to fine-tune the audio character from neutral precision to subtle tonal adjustments. This flexibility makes the DAC a perfect fit for those who enjoy tailoring their audio systems to their unique preferences.

Precision Engineering for Flawless Performance

The DSH-805 is engineered for sonic purity and reliability. Its internal master clock minimizes jitter across all digital inputs, dynamically selecting the optimal frequency for precise timing and natural dynamics. USB inputs feature galvanic isolation to shield the audio path from interference caused by computers or mobile devices, ensuring stable and high-quality signal transfer.

The DAC’s linear power supply, built around a custom-designed Polish transformer, delivers low noise, stable voltage, and ample power reserve. Five independent secondary voltages isolate the digital and analog sections, while a dedicated reference voltage regulator enhances conversion precision, maintaining optimal dynamics in all listening conditions.

A Design Rooted in Unitra’s Legacy

The DSH-805’s sleek metal housing and brushed aluminum front panel reflect Unitra’s iconic design heritage while offering robust protection for its advanced electronics. The front panel features a functional LED matrix displaying the active source, selected filter, and signal parameters (sampling rate, format, MQA, and DSD), blending modern technology with a nod to the golden age of audio. The DSH-805 pairs seamlessly with Unitra’s flagship WSH-805 amplifier, creating a cohesive and visually striking hi-fi system.

Proven in the Real World

The DSH-805’s performance was rigorously tested at the Takt vinyl pressing plant, where digital-to-analog conversion is a daily necessity for creating high-quality vinyl masters. These tests confirmed the DAC’s ability to deliver natural, consistent sound under the most demanding conditions, solidifying its place as a top-tier audio solution.
