For the sake of sharing excellent audio performance, I post this audio for those who may still wonder about a choice of excellent preamp for location recording.
The context;
My battery powered Quadmic II unit, full frequency range, merely set at mid and ISO-gain.
Four DPA compact capsules arranged in my dedicated enhanced binaural gear setup.
The file is a medley of public audience to capture the immersive space, a clap to assess the sound decay, and an excerpt of Cesar Franck's piece for organ.

Again, more than very convinced by the box for high-end location or various ambient recordings.
