SE300 B (discontinued) is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from A Classic Microphone Component That You Can Trust I purchased this and the CK 93 hypercardioid capsule for film production dialog recording. The SE300B is now made in China, but other than slightly mismatched paint, seems to be robust and manufactured according to the published specifications. I appreciate the simple, sturdy Modu-lok system, and the ability to have multiple capsules for this one powering unit greatly simplifies my kit when traveling. Lastly, the sound I get from recording with this pleases me greatly.
