never used the M179 but CAD mics are very well made mics, you just have to know what you are getting because they have a character to them very much like Blue mics do. Look at the freq specs and match it with what you are going to use the mic for whether it is drums, vocals or guitars. I just got the CAD Trion 7000 and I like it. The mic can take a pretty high SPL but like other ribbon mics, they are a bit gain hungry so you have to be careful with the blending, otherwise, mixdowns are going to be a pain.
