100% agree Sarma. Almost any microphone will give satisfactory performance across the 300 - 2700 Hz passband used for SSB. Instead of spending huge dollars on high performance microphones, SSB operators would do well to spend any extra audio money for microphone processing. Equalization for leveling out or emphasizing critical portions of the SSB passband, noise-gating to remove ambient low level noise, and compression to raise the average talk power. "Thumping" bass response and crystal clear highs are both thrown away by the SSB filter anyway. So the smart money would be spent limiting dynamic range and emphasizing intelligibility within the remaining response.
