EM272 and EM273 appear to be exactly the same element with a
different wiring. The 2-wire version has higher sensitivity,
because of the gain of the FET in common-source mode, when the
lower sensitivity of the 3-wire version is the result of the FET
being used in common-drain mode.
In simpleP48, the circuit is common-source, so there should be
little difference between a native 2-wire capsule and a 3-wire.
However, the Jerry Lee variant allows decreasing gain at teh
benefit of max SPL.
This can be done only with a 3-wire capsule (or a Linkwitz
modified).

The Primo EM273 is similar to the EM272 but with higher SPL
handling (135 dB vs 119 dB). Also, the simpleP48 doc has a few
ideas about increasing the SPL headroom of some capsules.

The LOM basicUcho have a slightly different capsule mounting
(flush, vs the slight rim of the Clippy case), which might
account for some of the sound difference. I always flush-mount
the omni capsules in my mics.
