I am aware of the physical differences between these mics, but how do they sound compared to each other? I would expect the '40 and '8040 would be quite similar and the '800 less so, but I don't really know.
I have a weakness for multi-pattern mics, so maybe I should get some MKH800s, but that is some serious coin. Now if Sennheiser would just make a stereo version of the MKH800 I'd be all over that.
I edited my subject to make it clear I'm asking for opinions rather than offering an opinion. Sorry for any misunderstanding.
