Thanks for including the Rode SVM in your chart I was unfamiliar

with the SVM.  It's a 9V battery-powered single-point stereo mic
designed for use on a video camera.

At a price of only $250, the SVM looks like a good match for "point
and shoot" recorders like the Marantz PMD620, Edirol R-09, Tascam
DR-1, and M-Audio Microtrack II, all of which have preamp noise
performance around -110 dBu.
