I would also add dynamic range to the conversation here.
Self-noise can vary wildly between mics under 500 and over 1000 of course, =
but I often find I can hear the difference in dynamic range more. The same =
applies to lenses, to follow the photography analogy.
That is why, to my ears, at least, a 750=80 Neumann km sounds better than a=
200=80 Rode nt1a, even though the noise specs of the Rode are better.
Another thing I=92d like to add is that it=92s about your end product as we=
ll. If you=92re gonna be playing your recordings on a home system or throug=
h headphones, the differences are small. I=92ve made great recordings with =
the built-in mics of my Sony D-50 that way. However, when I play these reco=
rdings on a theater PA system, or in a high end professional film studio, t=
hey don=92t sound as great anymore.
So yes, I=92d say there definitely is a (big) difference between low price =
and high price microphones, but there=92s many occasions and circumstances =
where that shouldn=92t be an issue. And more importantly, it should never s=
top you from recording.
