Wattson Madison Amplifier
A compact Class A/B power amplifier, developed in collaboration with CH Precision.
The Madison Amplifier was developed through direct engineering collaboration between Wattson and CH Precision. It combines a low-feedback Class A/B linear circuit, a robust regulated external power supply, and a fully symmetrical discrete amplification stage in a compact form. The same bipolar output devices used in CH Precision's M10 Reference Amplifier ensure predictable behaviour and harmonic integrity across demanding loudspeaker loads.

What it solves
Engineered to deliver accurate sound in real rooms, not just anechoic chambers.
CH Precision collaboration
Developed with the same engineering team behind CH Precision's reference electronics, using identical bipolar output devices from the M10 Reference Amplifier.
Configurable operation
Supports stereo, mono, and bi-amp modes via rear-panel switches, adapting to different loudspeakers and evolving system requirements.
Fully symmetrical discrete design
From balanced XLR or single-ended RCA input through to the output stage, the circuit remains fully symmetrical and fully discrete for structural consistency.
Swiss billet aluminium chassis
Machined from solid aluminium billet for electromagnetic shielding, mechanical rigidity, and thermal stability. Manufactured locally using sustainable practices.
