Acoustic truth does care about not introducing noise into the environment you wish to place treatments and embeddings. I am referring to signal noise that smears, perverts, and masks the audio signal. So the gear and tweaks audiophiles buy certainly play a role at reducing signal noise. Gear, modifications, tweaks, room treatments, vibration control, component matching, speaker placement, room construction, listening skills, subjective preferences and so much more all play a role in this passion. They all matter. How one comes to realize sonic contentment is a complex meshing of all of this. No one road is the universal way.
@mahgister I have looked at your virtual system many, many times and what you have done is so remarkable and interesting. Your perspective is valuable and yet another important piece of the puzzle.
