It's pretty simple. Listen to some highly processed, non acoustic music. Judge it. I'm doing it right now. My judgement? It sounds good...It seems you confuse taste with acoustic science here...
Feel free to judge your system playing minimally processed acoustic music.
You dont get the point: our brain are linked to recognise voice TIMBRE for million years and a natural piano timbre we know already what it is for all our life, we can separate here the artefact aspect of the sound and his natural aspect ... But how are we supposed to know how would be the sound of any ELECTRICALLY processsed instrument? Where do you separate the "artefact" from the "natural" in the timbre of an electronical instrument?
A moog synthetiser...A theramin.... An electrical guitar....It is way more difficult here to separate what pertain to an artefact and what pertain to the natural....The border between the 2 dont absolutely exist....
