I've already done that; but, let's take one measurement, signal to noise ratio. If one component measures 100db and another unit measures 101db that means the unit measuring 101 will sound better even though you would not be able to distinguish it as sounding better. That's to say you could not hear it.
Let's define "SOUND".
Sound Wave travels through the air and enters our ears, which is converted to electrical impulses and is sent to the BRAIN.
We're not robots, so our brains do not interpret the sound as one's and zero's.
If your brain cannot distinguish between 101dB vs 100dB, then the S
OUND will be the same.
SOUND is what our brains actually hear/perceive/interpret/distinguish, not the difference in measured numbers.
Wait a minute, are you a bad robot?
