Introduction

Stellar DAC brings wonderful imaging and musicality to any high-performance system at a price you can afford. With a clean, rich tonal balance and pinpoint imaging, it can serve as the centerpiece of your music setup. Featuring a built-in Digital Lens reclocking circuit, dual I²S inputs, selectable digital filters, and a hand-matched Class-A analog output stage, it reveals the full depth and detail of your music library.

Design

Engineered as an affordable, high-performance digital-to-analog converter, the Stellar DAC centers on the ESS Sabre 32-bit Hyperstream DAC chip, fed by PS Audio’s proprietary Digital Lens technology to eliminate jitter. Its fully balanced Class-A analog output stage, supported by multiple dedicated power supplies, ensures lush, detailed, and distortion-free analog reproduction.

Application

As a full-function DAC, the Stellar DAC accepts any digital source—from PCM up to 384 kHz to DSD256—and outputs low-distortion, high-resolution, fully balanced analog. It can replace both a preamplifier and DAC in your system: simply add a power amplifier and speakers, then use the built-in lossless volume control to enjoy reference-quality sound within moments.

Technology Overview

Stellar DAC converts incoming digital signals to near-perfect data with its FPGA-based Digital Lens, then passes them through the ESS Hyperstream architecture for exceptionally low noise and distortion. The hybrid design integrates a capacitor-free output path and a high-current, oversized analog power supply, preserving transient detail and dynamic impact. Multiple digital inputs—including USB, optical, coaxial, and dual I²S—provide versatile connectivity options for any source.
