Weiss DAC204 D/A Processor Delivers Precision in a Compact Package
Weiss Engineering’s DAC204 continues the brand’s legacy of audio excellence, blending professional accuracy with a streamlined design that’s both functional and elegant. Crafted in Switzerland and envisioned by digital‑audio pioneer Daniel Weiss, the DAC204 offers standout performance at an accessible price point.
A Legacy of Innovation and Studio‑Grade Design
Daniel Weiss, who founded Weiss Engineering in 1984 after his work at Studer, built the company on the principle that mastering‑grade equipment deserves to be translated into the audiophile realm without compromise. The DAC204 embodies that philosophy with its minimalist form: no display, menus, app support, or volume control—just reliable digital inputs, analog outputs, and durable construction befitting both pro audio and high-end home setups.
Smart Simplicity and Essential Features
Despite its streamlined interface, the DAC204 is highly capable:
-
Inputs: USB‑B, Toslink optical, and coaxial S/PDIF.
-
Flexible DSD handling: Converts DSD64/128 to PCM, with user‑selectable down‑sampling—recommended at 24‑bit/176.4 kHz.
-
Oversampling: Utilizes a single ESS Sabre ES9018S with four parallel Sigma‑Delta chains per channel.
-
Analog outputs: Balanced XLR and single‑ended RCA, with rear-mounted attenuator switches offering –10 dB, –20 dB, or –30 dB reductions for seamless integration with varying system gains.
-
Rugged case, simple toggles, and clear LED indicators streamline the user experience.
State-of-the-Art Measurements
Stereophile’s John Atkinson confirms the DAC204 achieves “state of the digital art” performance:
-
Channel separation exceeds 120 dB below 3 kHz, maintaining 113 dB across the audioband.
-
Near‑perfect linearity (output error negligible down to –136 dBFS).
-
Measured resolution approximates 21 bits, with exceptionally low distortion—third‑harmonic distortion at just –114 dB (0.0002%) with 1 kHz signals.
-
Extremely low noise and jitter across all inputs.
Listening Impressions: Clarity, Space, and Musical Vividness
Reviewer Robert Schryer praises the DAC204’s ability to imbue recordings with vivid detail and spatial realism. Instruments seemed to inhabit their own sonic presence within a larger stage, elevating both technique and timbral nuances. User impressions echo that sentiment, highlighting consistently lifelike detail, rich texture, and a truly immersive listening experience.
