Wattson Audio Madison Amplifier

The Wattson Audio Madison Amplifier is a compact, high-performance 2-channel power amplifier designed for serious hi-fi systems. Developed in collaboration with CH Precision, Madison combines a fully discrete symmetrical circuit, low-feedback Class A/B amplification, and a robust external power supply to deliver speed, stability, transparency, and musical control in a remarkably compact chassis. Key Features Compact 2-channel power amplifier Stereo, mono, and bi-amp operating modes Developed in collaboration with CH Precision Low-feedback Class A/B linear amplification Fully symmetrical, fully discrete circuit architecture Balanced XLR and single-ended RCA inputs External regulated and filtered power supply Switchable gain: +20 dB or +26 dB Solid billet aluminum chassis Available in Light Gray or Dark Gray Designed and manufactured in Switzerland Why We Love It The Madison Amplifier is a strong fit for listeners who want serious high-end amplification without oversized chassis design or unnecessary complexity. It has the engineering credibility of Wattson Audio’s collaboration with CH Precision, but its compact size and flexible operating modes make it practical for real-world systems. The ability to run in stereo, mono, or bi-amp mode gives it long-term system value, especially for customers who may want to scale their setup over time.
