| The old (non AI) U87 and the U67 use the same capsule. The old U87 is quite a bit noisier than the the AI version but has a transformer and can deal with higher SPL, like Peter said. One big problem that makes the U87 sound worse than any U87 is the distortion and lack of headroom. You can actually mod an old U87 to sound relatively close to a U67. If you need 2 matched U67 or U87, send them to Thiersch for reskinning and get all the resistors etc. matched by the same person that's doing the mod for you. |
