If you own a Toyota Prius upgrading its tires to the racing variety isn’t going to turn it into a Tesla. Nor would swapping tires with the Prius significantly alter the Tesla.
Yet better tires definitely improves performance when paired with the right vehicle.
The same can be said for our hifi systems. An expensive cable won’t help much on a consumer level stereo nor would a consumer level cable cripple a state of the art rig.
Polish and incremental improvements matter most when paired with products at the peak of their performance.
