Here's a comparison of the H47 and a vintage u47fet. The audio bounces back and forth between the two mics. I made the cuts arbitrarily so as not to favor one over the other. There's no processing whatsoever on these files, other than to match the volume. The vintage mic is on the top and the Heiserman is on the bottom. Below I'm also including links to the raw wav files on dropbox.

We'll be posting a lot more audio clips in the coming days....
