Our ears are by far the most sensitive organs we have. The eye only can guess: f.e. try to determine a distance from 3 meters away. You NEVER will get closer than an inch to the real distance. Now measure a musical octave which means doubling of the frequency. Even an untrained ear will hear a difference in tune/pitch of much much less than a quartertone! The ear's range is much superior to the eyes' range. If we could see with the ears's dynamics we would turn blind immediately....and so forth. That's why burning in any electronic device is a process of reality because it addresses our hearing. The better your high end system the more you hear the difference between new and burnt in!
Good luck - and just trust your ears!
