Here is a truly unique pair of Amplifiers, they were originally slated to be built for (CENSORED) by Canary Audio, this smaller Version and a larger one - reminiscent on the mighty Canary Audio Reference two we also have listed here on Audiogon.
This is Basically the leftover chassis parts form that decades old build - Stunning Cool looking meters to boot too. With internal parts like the Mighty Canary M500/600 Mono blocks. These come with a full compliment of tubes, PS Vane 300B outputs too.
Below is some information on the Canary M500/600 from their website: M600 Monoblock Amplifiers Built around 300B Triode Tubes:
The M600 is a class A triode mode, push-pull parallel monoblock power amplifiers with 300B output tubes. It is the upgraded version of the M500 with the use of highest quality parts and components such as Amtrans AMRG premium carbon film resistors. It has a newly designed integrated power curcuit with time-delay relay to eliminate turn-on thump.
The M600 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 M600 monoblock power amplifiers are specially designed for optimum sound quality. Deliver high power music at wide dynamic range with ultra low distortion, the M600 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. Special Features: Amtrans AMRG premium carbon film resistors with gold-plated leads.Integrated power curcuit with time-delay relay to eliminate turn-on thump.Newly designed high voltage power supply.Rectifier with double choke filtering (two chokes are employed per channel).The input circuit has been redesigned to be faster and more dynamic. Custom EI power transformers.Exclusive machined Delrin 300B tube sockets with gold plated pin receptacles.Specially designed power meter with a custom backlite LED display.100% handcrafted in California, USA.
