Presonus M7 Review - A Rough Start

That out of the way, these are my thoughts on the M7 by Presonus. It was the first Mic I picked up as part of a kit; it was the old Studio One package before they released the newer USB96 version. Maybe they've made significant improvements to their hardware since. It's also a pretty unfair comparison to rate this against something like a Rode, but I figure this will provide you a working idea as to the quality of this particular microphone.
Edit:
For a bit of clarification, both mics were tested w/ the same mixer & preamps - the gain level that was set was calibrated using a 200hz sine wave (the M7 needed significantly more gain, which you can hear w/ the background noise), both recordings were captured within proximity effect distance and finally normalized in post to -3db. Aside from this, zero processing or compression were done - meaning no noise gating, either. Both were recorded in a regular room - aka untreated environment - aka the type of environment you'll most likely be recording in unless you've taken a stab at sound dampening or acoustic treatment.
