As usual for Canary Audio the build quality is superlative using the finest internal components and the chassis work is on a lofty level compared to anything on the high-end market today.

These M-80 mono-blocks offered the highest level of purity of tonality/timbres, lifelike imaging both in the size of the sound-stage, along with 3D imaging with air between the different instruments, and that silky, grain-less ease that only a SET design can produce. However, strikingly compared to other 300B SET amplifiers that I have reviewed, the Canary Audio SET M-80s added powerful macro-dynamics, pressuring my large acoustic space in a way that you’d think could only be done by a 100-watt amplifier! This did not come at the expense of musicality or a natural presentation. When the recording venue had a very large space and was big on macro-dynamics/sub-sonics, the M-80 mono-blocks gave me the total experience in a powerful way. These Canary Audio mono-blocks serve up beautiful representations of acoustic music (Jazz,Classical,Vocals). However, if you want to “rock out” to hip/hop, rock, rap, dance music, electric, and big orchestra pieces, you want to have the M-80 mono-blocks driving your system.
