How we ranked these mic preamps
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: small microphone preamp
Match gain to your microphone
Gain figures differ across this list. The CL-100 gives 25dB, the FOSA and Yunir preamps each give 20dB, and the DPM1L gives 29dB. A dynamic microphone with low output needs more gain than a condenser microphone with a hotter signal, so check the gain figure against the microphone you own.
Check phantom power and connections
Phantom power matters only if the microphone needs it. The CL-100, the FOSA preamp and the Yunir preamp each support 48V phantom power with an XLR output. The DPM1L connects with direct XLR male-to-female connection and needs no drivers. Match the connections row to the interface or mixer you already own.
Look at size and housing
A preamp that lives on a desk can be larger than one that rides in a bag. The CL-100 measures 5.8x2.5x2.5 inches in an orange and black metal housing, while the DPM1L weighs 1.76 oz in a red and black metal housing. The MP13 measures 5.0 inches on each side. Check the size row before buying, so the preamp fits the space you have.
