Hello,
"LOL that couldn’t be more untrue" : everything can be true depending of your POV, i've work with engineers that don't know ANYTHING about elecrtonics, but i've understood that my starting point was a banana peel and you see it from your POV.
"Dynamique range, noise floors, Q THD, frequency etc"
Dynamique range : aroud 30-40Db for the recordings plus 30Db for for the band pass
Noise floors : under -90Db at the output, the source is over -100Db.
Q : i was looking for 0.2 but i can't obtain more than 2.5 with the simulations
THD : lowest possible.
Frequencies : have to be defined by measurements, but everything is under 50Hz
