From there on, I've tried to experiment with their other microphones on sources I less commonly record. Their new Nuvo series, active ribbon microphones with a nice price tag and a slimmer, more modern form factor, are marketed as great all purpose modern ribbon microphones with condenser-like gain requirements and a full frequency response.
The key difference between them is that the N22 has a reduced proximity effect, making it useful for close mic recording of vocals, acoustic instruments - pretty much anything. Sometimes proximity effect is actually wanted though, and along comes the N8 - a much warmer, low frequency heavy mic that performs extremely well as a room microphone where it's not right up close to the source.
Here's how both models sound on a lovely new custom made Taylor Grand Auditorium shape acoustic guitar, with a classic AKG C414 large diaphragm condenser mic set to bi-directional polar pattern for comparisons sake. This should give you a good idea of how differently the ribbon microphones respond.
