$300 for a tube mic seems pretty insane to me but I have heard that the CAD M9 is decent. I guess the tube warms things up sufficiently. I'm looking for something that can handle vocals and acoustic guitar. Anyone used one of these? Too good to be true?
As far as tube mics go, I've used the CAD M9, the ADK Generis GT-2, and the Karma K58. I like the ADK if I'm going for a smoky, breathy sound, while the M9 gives a rounder, smoother sound that I think sounds pretty universally good once it warms up.
Note: the CAD M9 sounds harsh before it warms up, and for a brief period while it is warming up, it sounds absolutely awful.

You
must wait for this mic to warm up if you want it to sound good.
About the NTK, it's one of those mics that people either love or hate. I've heard people saying both around here. The people who don't like them describe them as brittle, harsh, and/or hyped.
Considering the CAD costs about half what the NTK costs and is almost universally liked, I know which one I'd pick....
