Even then, you can still get nearly perfect measurements for two devices and still hear a difference, especially when comparing R2R and sigma/delta chips. Some of this might have to do with the ultrasonic noise and filtering techniques as well that go beyond what your ADC's sampling rate might pick up, but this is starting to get outside of my limited knowledge area.
Most of this has to do with processing artifacts in your brain, you'll have to upgrade the wiring in your auditory cortex and install new supramarginal and angular gyri to be sure.
Make sure to use the right instrument.
