PS Audio NuWave DAC

Description

The PS Audio NuWave DAC is a compact yet capable digital‑to‑analog converter aimed at audiophiles who want solid performance and flexible connectivity without the high price tag of flagship models. Designed as an evolution of PS Audio’s earlier Digital Link series, the NuWave brings several advanced digital features from its bigger stablemates into a more accessible package. It is ideal for upgrading computer audio, CD transport outputs, and other digital sources to high‑quality analog output.

At its core, the NuWave DAC uses a 24‑bit/192 kHz‑capable conversion architecture built around a Burr‑Brown PCM DAC chip (such as the PCM1798) that supports high‑resolution audio up to 24‑bit/192 kHz via all inputs. It offers asynchronous USB input, which allows the DAC to control the timing of incoming data instead of relying on the source device’s clock, reducing jitter for cleaner audio reproduction. In addition to USB, it typically includes both coaxial and optical toslink digital inputs for versatile source connections.

One of the notable design attributes of the NuWave is its fully discrete analog output stage. Instead of relying on generic op‑amps, PS Audio developed a high‑current Class‑A output stage made from discrete transistors and FETs for robust signal drive. This section feeds balanced (XLR) and unbalanced (RCA) outputs, allowing integration with quality preamplifiers and integrated amplifiers while maintaining signal integrity.

The NuWave’s digital processing architecture includes low‑jitter clocks derived from PS Audio’s higher‑end PerfectWave designs, helping to keep the digital‑to‑analog conversion stable and accurate even with complex material. It also provides both “native mode” (no sample‑rate conversion) for faithful reproduction of the source signal and an optional upsampling mode to 192 kHz for users who prefer a smoother sound at higher resolutions.

In terms of sound quality, reviewers generally find the NuWave to be smooth and engaging—with a relaxed presentation that is easy to listen to over long sessions. While not as highly detailed or analytical as more expensive DACs, it offers enjoyable performance for its price bracket. One reviewer noted that the NuWave’s rendering of high‑resolution (192 kHz) material brought out a “huge soundstage” with convincing depth and separation, especially when compared to native 44.1 kHz playback.

The NuWave’s minimalist design philosophy is also reflected in its simple front‑panel controls and LED indicators, with no remote control or complex display. This keeps the unit easy to use and ensures that focus stays on performance rather than user interface bells and whistles.

Today, the NuWave DAC remains a value‑oriented entry point into higher‑end digital audio from PS Audio. It is often found on the used market, where buyers appreciate its combination of balanced connectivity, asynchronous USB support, and classic PS Audio engineering in a half‑width chassis.
