Well Raul, to make a long story long, I will tell you a minute part of what I've done to have unaltered music.
To begin with, I have custom speakers (don't recommend it, wouldn't do it again) ; they are so neutral that the slightest change in interconnects is easily detectable.
First I engaged a "cross over design engineer" to guarantee they would have no sound of their own; then we selected the drivers; they're 3 way. (if the thought ever crosses your mind, the cross over is one part you can't leave to guess work)
While I've heard a multitude of other speakers that have personality which I've enjoyed; such as Klipsch, and JBL, I know mine deliver the musicians intentions, and the bottom line for me, is always the music.
