Perfect sound, like jumbo shrimp, deafening silence, and bittersweet are oxymorons: contradictory terms that form new meaning.
Sound cannot be perfect because that would mean without any flaws or interactions from its point of generation to your ears. Even a wisp of wind, or a change in temperature along the way would alter the sound before it reached your ears.
Trying to achieve perfection in our audio systems is a lofty unattainable goal.
Perhaps we would be better served to consider instead, striving for musical connection. The deeper the connection between you and the music the closer to the ideal.
We wince at a bit of brittleness or harshness, but feel drawn in deeper when everything is just right.
We'll never hit perfect but we can be so connected that it really doesn't matter anymore.
