https://www.goldenageproject.com/microphones-2/r1-active-mkiii i basically bought it based on the positive review of the sound on sound mag (Ribbon Mics On Test).i already own one ribbon mic, the cheap t.bone rb100 which sounds "ok" but rather muddy and dark. Output impedance is low at 50 ohms and SPL handling is high at 150dB. It has the natural and warm sound of classic ribbon microphones. just got my new Golden Age Project R1 MkII ribbon mic. i needed a better one for vocals. The amazing high Max SPL give it the ability to handle loud sounds, like overhead, guitar cabinet or even kick drum. Golden Age Project R1 MK2 is a vintage style ribbon microphone. 2.
