Key Kim, Senior Editor at Stereo Times, selected the M350 and C1800 MK-II as Stereo Times’ Most Wanted Components of 2020.
The M350 was reviewed by Key Kim, Senior Editor at Stereo Times, on March 2, 2021.
Built around 300B transistors: The M350 is our latest 300B mono amplifier. Each channel draws power from two pairs of matched 300B transistors, and each channel of the M350 is capable of delivering 50 watts of power. This is achieved through the use of a mass-produced custom-wound power supply and output transformer designed specifically by our engineers. The newly designed circuitry provides greater power, deeper bass extension, quieter operation, and improved dynamics. Like all other Canary products, the M350 is 100% handcrafted in California using the finest parts and components.

M350 monolithic power amplifier is specifically designed for optimal sound quality. Delivering high-powered music with ultra-low distortion across a wide dynamic range, the M350 is simply the best amplifier one could ask for. A muscle canary may not exist in nature, but if it did, it might sound like something from this amplifier.
