Shure SM7B tldr

The Shure SM7B is a fantastic microphone. When setup properly this thing produces crisp, clean, professional audio with the lowest of noise floors; even in less than ideal conditions.

You don’t necessarily need a cloudlifter at all. I just recorded a podcast and had a cloudlifter on only one mic. Turned up the gain on the other and it was fine. I like the cloudlifter, and will probably buy a second at some point, but it’s not a necessity. Give it a try and if you need the cloudlifter, get it later.
