Cloudlifter CL-1 - $100

Mint Cloud Microphones Cloudlifter CL-1 adds umph to your dynamic mics Low-gain microphones typically come with high-impact problems that can frustrate engineers.
Unfortunately, many dynamic microphones are among the best sounding models out there.
Luckily, there’s the Cloudlifter CL-1 Mic Activator by Cloud Microphones — a perfect solution to any situation in which you need to cleanly boost a microphone signal before the preamp.
Driven by the phantom power circuit on board your mixer, the Cloudlifter CL-1 adds up to +25dB of perfectly transparent gain to your signal, giving low-output mics a major boost, which makes budget microphones sound clean and professional and quality mics such as the SM7B sound absolutely fantastic!
