Lives for gear

Exactly. The mike maker has to use more internal gain to make the sdc as hot as an lcd. Electronic circuits always add brownian noise, and the more gain, the more noise. This is before you add more gain with preamps and compressors.

Take Rode as an example:

NT2A and NT2000 (lcd) have an EIN of 7dBa.
NT3 (sdc) has an EIN of 17dBA.

That's an extra 10dBa of hiss, before you get to your preamp.

Quite low compared to vintage stuff, and certainly useable. But I don't like to add 10db of hiss unless I really need like the sound.
