I've seen a number of recordings online listed with a Superlux SMK-H8K/C as the primary source.
However, a google search on this topic only reveals more recording sources and lineage, but no information about the equipment.
A search on tts focusing on Microphones & Setup and Recording Gear also turned up an amazing 0 results.
Perhaps this is too simple a question, easily answered in one reply, my apologies.
