Wattson Audio's definitive streaming DAC, combining proprietary spline filtering with Swiss precision engineering.
The Madison Streamer is Wattson Audio's definitive expression of digital playback and control. Designed and engineered entirely in Switzerland by the same team behind CH Precision, it combines a robust analog output stage with advanced DSP architecture. Its proprietary Spline filter, derived from CH Precision's reference designs, is optimized for temporal accuracy where musical coherence lives. Supporting both network streaming and S/PDIF digital sources, the Madison delivers balanced and single-ended outputs for seamless integration with any system.

Engineered to deliver accurate sound in real rooms, not just anechoic chambers.
A time-domain-optimized upsampling algorithm derived from CH Precision's reference designs, minimizing pre- and post-ringing for superior transient realism and rhythmic integrity.
Developed with CH Precision, operating in precise 0.5 dB steps verified to within ±0.1 dB. Preserves microdynamic nuance whether used as a digital preamplifier or feeding an analog stage.
Dual WM8742 DACs - one per channel - ensure superior separation, spatial coherence, and tonal purity for faithful musical reproduction.
Noise levels below 1 µV RMS (10 Hz–100 kHz) with dedicated filtering and regulation for each critical subsystem, from clock generators to the analog output stage.
