In order to avoid misleading or false information on microphone forums (in this case mine) I'd like to find out whether Neumann offers (at an up-charge) capsule matching for K67 (in case of replacing two defective USM69 capsules) or matching a pair of U87Ai; and also whether Neumann will match K86 replacement capsules so that both sides of a KM86 are uniform.

Thanks in advance,
Klaus Heyne
