Gutbucket, a late add-on: You're right, of course, but please keep in mind that a narrower stereophonic recording angle (to use Michael Williams' term) leads to greater discrimination between left and right channels and thus a wider-sounding stereo image in playback. I'm fairly certain that the previous post meant that.
To repeat, the fundamental problem with the NT4 is far too wide a stereophonic recording angle (180°!), which in turn leads to a near-mono pickup of centered, distant or semi-distant sound sources. Usually an SRA of distinctly less than 100° is preferred (YMMV of course).
