The simplest recording signal path on the planet?

Is it the following?


One omnidirectional in ear capsule in each ear one for each recording reproducing channel.


Musicians playing softly so that there is high average to peak signal and so it sounds loud without the need of compressor, peak limiter etc.


This will require low noise preamps. JFETs or electron tubes with reduced heater voltage, high resistance from anode to grid and low battery anode (plate) voltage.


On the recording device side instead of the load resistor would it be even better with a JFET? So when mic with its JFET is connected to the device the configuration becomes cascode (one JFET on top of each other).


But could it be that just a low noise load resistor is simpler and better?


If dynamic in ear capsules are used, the signal may be stepped up with a Pleiades input transformer using a Magnetec Nanocrystalinne Nanoperm core before feeding the active devices.


If instantaneous peak limiting is needed maybe the Pleiades V5 preamplifier is the simplest signal path with just 2 EF183 electron tubes and very few components, battery powered.
