I completely agree, while the inverse is also true—acoustics cannot do what good tweaks do. It’s not an either-or situation, nor does one negate the need for the other. Acoustics, speaker placement, proper system setup—including impedance matching, matched electronics, proper power for speakers, and proper subjective balance of electronics for speakers in the room—alone will not achieve what tweaks do. Tweaks enable everything else to work that much better.
The relationship between acoustics and tweaks in audio systems is synergistic rather than mutually exclusive. Both play crucial roles in optimizing sound quality, and their combined effect is often greater than the sum of their individual contributions.
