The Weiss DAC204 is a compact, high-performance multi-format digital-to-analogue and digital-to-digital processor designed for both audiophile and professional use. Housed in a small Swiss-made chassis, it delivers reference-level conversion from USB and S/PDIF/AES sources. This pre-owned unit is in good condition in silver and comes with original packaging.
Despite its modest size, the DAC204 offers the kind of measured performance and format flexibility that has made Weiss a respected name in studio and high-end listening rooms.

Why Choose the Weiss DAC204 D/A Processor?
The DAC204 brings studio-grade conversion and digital routing into a remarkably small, well-engineered box.
• Exceptional Linearity: Less than ±0.4 dB variation from 0 dBFS to –120 dBFS.
• Very Low Distortion: THD+N down to –125 dBr at lower input levels.
• Professional Connectivity: AES, S/PDIF, Toslink, USB and BNC digital paths.
• Adjustable Output Level: Rear-panel switches set analogue output voltage to suit the system.
• Compact Swiss Construction: Serious performance without a large chassis footprint.
Audition the Weiss DAC204 at our Lane Cove showroom to hear its clean, highly resolved presentation.
Frequency response remains tightly controlled across sample rates, and crosstalk is specified at –120 dB from 20 Hz to 20 kHz.
Interchannel phase accuracy is excellent, supporting precise imaging. The combination of USB computer audio and conventional digital inputs makes the Weiss DAC204 equally at home as a desktop converter or as a compact source in a full system.
For listeners who want Weiss engineering without a large component, the Weiss DAC204 remains one of the most capable small-format processors available.

Condition is unknown, so the price has to do the heavy lifting, and at A$4,000 it lands right on the median of recent AUD comparables for this model. That makes it a fair ask rather than a bargain or an overreach, especially given the narrow spread between the 25th percentile at A$3,421 and the 75th at A$4,275.
That still makes it a worthwhile buy if the unit is complete and functionally clean, because the DAC204 is well regarded for its very resolving, low-noise, “get out of the way” presentation and strong digital processing flexibility. For a used piece at this level, the real upside is in a careful seller, original packaging, and proof it’s been problem-free; missing accessories or vague history would matter more here than on a cheaper DAC.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Weiss Engineering was founded in 1985 by Daniel Weiss in Switzerland, near Zürich, following his five years at Willi Studer AG where he pioneered digital audio innovations like sampling frequency converters and processors for recorders. A self-taught electronics enthusiast who built his own synthesizers, amplifiers, and even an electric violin in his youth, Weiss established the company to specialize in digital audio equipment for mastering studios, launching the modular 102 Series that remains relevant today at 24-bit/96 kHz. This heritage in professional signal processing laid the foundation for the brand's precision engineering ethos.
The company focuses on high-end digital audio components, excelling in digital-to-analog converters (DACs), CD transports, streaming devices, preamplifiers, and integrated amplifiers, all designed and manufactured in-house by a small team of eight. Early products like the Gambit Series—featuring standalone equalizers, dynamics processors, de-noisers, and converters with 40-bit floating-point processing—targeted mastering engineers, while the 2000 expansion into hi-fi introduced audiophile favorites such as the MEDEA DAC and Jason CD transport, now staples in discerning home systems worldwide.
Weiss Engineering occupies a niche boutique position at the pinnacle of the high-end hi-fi market, revered for its Swiss-made transparency, ergonomic excellence, and unmatched digital fidelity among knowledgeable audiophiles and professionals. Daniel Weiss's 2021 Technical Grammy Award underscores its authoritative status in digital audio, appealing to buyers seeking reference-grade performance over mass-market compromises.
