Finally, after many years, I have found a pair of original Neumann M7 capsules in perfect condition: no cracks, no holes, and the diaphragms are intact; they have likely been used very little and stored in a dry, smoke-free environment. These are the capsules originally produced by Neumann in the Berlin factory, identifiable by the serial numbers on the rim and the black thread on the capsule ring. I have never installed them and consequently never listened to them, so consequently, I am selling them as untested. I will limit myself to this: an M7 capsule with a replaced diaphragm loses 50% of its performance and sound quality. The price is for the pair; if you only want one, the price is €1800, although I would prefer not to separate them since they date back to the same era and are assumed to sound the same... (matched)... I repeat, untested...
