Hi Munir,
This thread started because I was having noise problems with my new
MKH8020s. In the past week I have found out that there is a noise
issue with the entire 8000 series of mics, all the models, not just
mine (i.e. 8040, 8060, 8070). While some people have these mics and
they work OK, others find they have periodic loud fizzing noises in
the mics.
So no, definitely NOT, I would NOT recommend the 8000 series mics as
100% dependable.
Others might like to chime in on what mics they have found to be 100%
reliable.
