^^^ Good point. I'd like to add, that while I have the utmost respect for ClieOS, and his reviews/opinions, when it comes to things like treble harshness and sibilance, even he, can only go by his ears. Two iem's I'd like to use for examples, W3.....some say harsh/sibilant, others hear none of either. TF10, again, some would say harsh and sibilant, others (like me) hear no harshness or sibilance. So keep in mind that no matter how good ClieOS is at this, he is still restricted by his hearing being different from other peoples.
All he can do, is to give the most open and honest review possible from his perspective.
