M500 Mono Blocks Power Amplifier Built around 300B Triode Tubes:The M500 is a class A triode mode, push-pull parallel mono blocks power amplifier with 300B output tubes. It features a modified circuitry that guarantees a more dynamic soundstage with deeper base tones. Like all other Canary products, only highest quality parts and components are used in critical applications. The oversize custom wound power and output transformers are specially designed to handle twice of its power rating, ensuring durability. Two independent chokes are employed for rectifier filtering on each channel. The Muscular Canary:The M500 mono blocks power amplifier is specially designed for optimum sound quality. Deliver high power music at wide dynamic range with ultra low distortion, the M500 is simply the finest amplifier one could desire. Maybe the muscular canary doesn't exist in nature, but if one existed, it might sound something like this amplifier.
