How can a system be judged with highly processed, non acoustic music?


I basically know what an instrument or human voice sounds like. I understand that almost all recordings, analog or digital, go through some level of processing. I also know that there are many, many recordings which strive to present a natural, real sound. To me, I can best judge a system playing lightly or non processed acoustic music.
This is also my preference for listening in general. And for me, it is vinyl.

For me yes....

Metallica is like a very good detailed " white and black" drawing...At best....

A lute piece very well recorded is like a color oil paintings...Or a rendition of Chopin or Listz at the piano....

The sonic "cues" are way more subtle and evoke way more subtle mix of emotions...For me....

i like the group "Nightwatch" for example but i listen to only the albums with their first female singer.... The voice add to the group something more poetic and more natural....a unique set of colors.... She was a classical singer educated....


 Amplified or electronically amplified  instruments for me sound more "white /black" pixellation...And natural acoustical sound more like oil paintings...




never enough Frogman ;-) all good.
