Royer Labs dBooster
The Royer R-DB20 dBooster is a phantom-powered ribbon and dynamic microphone signal booster and impedance buffer. It increases the level of passive low-output ribbon and dynamic microphones with a minimum of distortion or coloration. Designed for professional applications, the dBooster provides two levels of clean gain boost; 12 dB and 20 dB, selectable by a front panel switch. The dBooster maintains headroom and gain regardless of load. The Class A input circuitry presents a high source impedance to the microphone, which minimizes loading (damping). This reduces coloration and distortion while at the same time improving headroom. By utilizing the 12/20 dB gain switch, optimum balance between gain and headroom can be achieved for a variety of uses. The low-impedance output of the dBooster is an increased microphone-level signal that can drive a digital interface directly or a standard microphone preamplifier. It also minimizes signal loss on long cable runs.

Does exactly what it says it does; big improvement doing tape sync w/ the SM7b, haven't used it yet for music or with ribbons but I'll bet it's great!
Works great with my r84 ribbon.. having the selectable gain is a bonus since I don’t usually need 20db boost.. I haven’t compared other types but I’m happy with the sound.
Great with the Royer R-10 I purchased, great combo!
