The Wattson Madison Amplifier is the kind of power amplifier that makes you stop fussing with the system and just listen. Co-engineered with CH Precision, it draws on genuine reference-circuit DNA—same bipolar output devices as the M10—yet arrives in a machined billet-aluminum chassis compact enough to tuck beside a streamer on any shelf. Its fully symmetrical, low-feedback Class A/B topology stays composed when loudspeaker impedances swing low, delivering transients with a snap that doesn't harden into brightness. Stereo, mono, and bi-amp modes mean it scales with your room and your ambitions rather than becoming a sunk cost. Quiet, fast, and structurally honest—this is Swiss minimalism applied where it actually matters: the signal path.

Liner Notes
The Madison Amplifier is built around a balanced, regulated, and filtered external switch-mode power supply with high current capacity. That supply is fundamental to the amplifier's performance, establishing the stability, dynamic authority, and composure that allow Madison to remain articulate across changing loudspeaker loads. Balanced (XLR) and single-ended (RCA) inputs allow the Madison Amplifier to integrate easily into a wide range of systems. From the input stage onward, the circuit remains fully symmetrical and fully discrete, preserving the amplifier's structural consistency whether the incoming signal is balanced or unbalanced.
The Madison Amplifier was developed through direct engineering collaboration between Wattson and CH Precision. That collaboration shaped the amplifier where it matters most: topology, power strategy, device selection, and overall circuit behavior. The result is a compact amplifier built with real structural seriousness. Madison's amplification stage is built around components derived from reference-grade designs developed with CH Precision—at its core are the same bipolar output devices used in the M10 Reference Amplifier. The Madison Amplifier supports Stereo, Mono, and Bi-Amp operation, allowing it to adapt to different loudspeakers and different system requirements without changing its underlying design.
Machined from solid billet aluminum, the chassis provides electromagnetic shielding, mechanical rigidity, and thermal stability, serving as both a structural frame and a heat management system. Manufactured locally using sustainable practices—including the reuse of aluminum off-cuts—the amplifier integrates environmental responsibility with engineering performance. The result is a simple and compact amplifier built with clear priorities: signal purity, configurability, and long-term relevance within serious music systems.
