Thanks for doing the test ,
The M149 recording is much louder than the K2 recording , when you take that into account the difference between the two is not so big.
Claiming that the M149 is better is just silly to me. The difference doesn`t make it better than the K2. Just different .
I think this is a fine example of how high-end gear costs more than it "tastes" .
Nice to have these things but we don`t NEED `em. And could do just as fine work with the moderately prices alternatives.
