The Wunder Audio CM7 aims for the sound of the first 200 U 47s, which used a larger, vertically oriented output transformer and the famed M7 capsule. Using premium passive components and a carefully-selected replacement for the original tube, the CM7 sports an enormous bottom-end and extensive high-frequency air -- the same sonic qualities as a perfectly-maintained U 47, making it an incredible lead vocal microphone that shoots the voice right into the soul of the listener.
