Design
The new StellarGold DAC, with its advanced parallel DAC architecture, takes advantage of performance standards unavailable to single DAC designs. By using multiple DACs in parallel, individual non-linearities of each DAC tend to average out. This is because the probability of all DACs having the exact same non-linearity error at the same digital input value is nearly zero. The results are nothing short of breathtaking. One listen to this DAC, and you’ll know it’s in an entirely different category from others at anywhere near its price range.
Application
PS Audio’s StellarGold DAC can become the centerpiece of a high-resolution 2-channel audio system. Using StellarGold’s balanced or single-ended outputs into our matching StellarGold preamplifier or, using its built-in lossless volume control, the StellarGold DAC can become the heart of a true state-of-the-art high-performance audio system at an affordable price.
PARALLEL DAC TECHNOLOGY
In high-performance audio DACs, employing four parallel DACs per channel offers a number of sonic benefits. First, it reduces noise through averaging, resulting in an impressive signal-to-noise ratio exceeding 127dB below the DAC’s maximum output of 4 volts (balanced). When noise is lowered, and the individual non-linearities of each of the 4 DACs are averaged together, the results are an increase in the effective dynamic range (loudest to softest sounds) and an audible improvement in linearity and distortion. The combined resolution effectively surpasses that of any single DAC of similar design on the market, creating an extraordinary audio experience that only a few people have yet to experience. We can’t wait for you to hear StellarGold in your system.
