Can someone give tl;dr? I watched first 20 seconds of the press and he keep saying 'I feel this I feel that'. How hard is it to make a point across, I don't have time for interpreting crap poetry.

I would assume it's just a degree of how much sound amplification/modulation and/or manipulation is made to the acoustic instrument or the recordings of it. Mind you, you don't even need to "record" if the original sound is made digitally/electronically which I guess can be considered non-acoustic or at least a very low degree of acoustic-sounding.
