It makes complete sense that the world’s foremost ribbon microphone manufacturer would get into the mic signal booster/impedance buffer game, as the performance of ribbon mics is greatly affected by the preamp with which they are coupled, and adding a signal booster/impedance buffer into the chain makes ribbon mics sonically compatible with virtually any mic pre. While some of the other products I’ve seen in this category perform well, they tend to alter the sound substantially (some even offer variable impedance to provide creative control of how the sound is altered) and they tend to add noise and distortion. That’s where Royer differs, as the phantom-powered R-DB20 dBooster ($179) provides the benefits of increasing the gain of a passive microphone without adding noise or distortion, and without altering the sound.
