Great initial impressions.
I am using the KM-A/KK143 combo for recording production dialog on set. It's specifically for the boom mic in quieter locations when there are two or more people speaking in fairly close proximity. This capsule is very helpful in unscripted productions.
Read more I don't have to worry as much about swinging the boom to each speaker and I can often park it more in the middle of a group. The other big benefit is that the wide cardioid reduces how much room reverb is captured. In fast moving productions there often isn't time to set up baffles or sound blankets. So in small, hard surface rooms this capsule is very helpful. So far I've only listened on my headphones and I've noticed how the capsule sounds extraordinarily smooth with no sibilance typically associated with more directional mics. I will also be buying the KK184 which may see more use on set as it has a desirable HF boost for dialog.
