If you can corroborate that Neumann will not sell you a capsule for a mic you own, and for which you can provide a serial number, please let me know and I will investigate what I can do about this.
I called Sennheiser in Connecticut this morning to get pricing and availability on a new Neumann K49 capsule. I gave the partnumber and was told that Neumann will no longer be selling any capsules, or any parts, for that matter. All microphones must be sent back to Connecticut for repair.
... just the courtesy I expect for spending thousands upon thousands of dollars on a company’s products.
Did you purchase and have you received the capsule?
It's a private company. They can make the rules they want. If a customer doesn't like that they can buy a competing product.
