How we ranked these mic preamps
Every pick has at least 100 customer ratings on Amazon and 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: microphone preamp
Match the gain to your microphone
Gain lifts a quiet microphone to a level your interface can use. The FetHead adds 27 dB, the Cloudlifter CL-1 and CL-2 add 25 dB, and the DM1 adds 28 dB. The TubePre v2 has a gain control instead of a fixed figure, so you set the level by ear. If your microphone sounds too quiet through your interface, an in-line preamp with a fixed gain figure is a direct fix.
Check phantom power before you buy
Four of the five preamps here use phantom power in some form. The FetHead runs on 48V phantom power through the XLR cable. The Cloudlifter CL-1 and CL-2 use phantom power without passing it to the microphone, which keeps passive ribbons safe. The TubePre v2 also has phantom power. Check that your interface supplies phantom power before you buy an in-line preamp.
Count the channels you record at once
One channel suits one microphone, while two channels suit two microphones at once. The Cloudlifter CL-2 has two channels, and the Cloudlifter CL-1, the DM1 and the TubePre v2 have one channel each. If you record two voices or two instruments at once, the two-channel pick is the one to compare.
Frequently asked questions
Do I need phantom power for an in-line preamp?
Most in-line preamps here need it. The FetHead, the Cloudlifter CL-1 and the Cloudlifter CL-2 run on phantom power from your interface. Check that your interface supplies it before you buy.
Will a preamp damage a ribbon microphone?
No, if the preamp keeps phantom power away from the microphone. The Cloudlifter CL-1 and CL-2 use phantom power without passing it to the microphone, and both are safe for passive ribbons. The FetHead is made for ribbon and dynamic microphones.
What is the difference between the CL-1 and CL-2?
The CL-1 has one channel and the CL-2 has two channels. Both add 25 dB of gain per channel and use phantom power without passing it to the microphone. Pick the CL-2 if you record two microphones at once.
Do I need a tube preamp for drive control?
No. The TubePre v2 is the only tube preamp here, with a 12AX7 tube stage and a tube drive saturation control. The other four add gain without a tube stage. Pick a tube stage if you want its drive control.
