Munir,
I have compared MKH20 mics with MKH8020 mics and I like the sound
from the MKH8020s much better - when they work that is! MKH20s are
better for nature recording with the Free Field switch ON, but are
still not as good a sound as the 8020s.
Many on this forum use Audio Technica 4022s which sound very good but
I've not used them to make a direct comparison. I've no experience
with any other brands.
