I used them as a cardioid stereo pair on different ensembles and shot them out against my two favorite Neumann pairs KM 54 and KM 84. The good news is, there is no winner!...Very open, beautiful stereo image, great frequency response, very natural, ... They are probably the only small diaphragm mics around that can keep up with KM54 and 84...Really good!
blew me away. Had it on a singer and as a center mic on a piano in an MS situation. Compared it to U67 and 47. The 47 is pretty different which was to be expected because of its capsule and the way it is built.
But the 67 - brought to the same level - is very, very similar. What a great mic!
