There are 2 instances where such a gizmo is useful, and I've been faced with both.I've been telling everyone who asks about cloudlifter type devices, "If you have a mic pre that will do 65dB or 70dB of gain you don't need one."
- The source impedance id too high for a mic input. This shouldn't generally happen, but my incursion in this domain was prompted by having bought a Thomann ribbon mic, which clearly didn't work satisfactorily. After some head-scratching I found its impedance was 2.5k. The 40+k input Z of a Fethead solved the problem.
- The line to the preamp is noisy. Adding about 20dB to the mic signal improves S/N.
One thing is for sure: none of these has a better noise figure than a good preamp coupled with a good mic and a good cable.
