Ok...so I decided to check it out for myself. Apparently at high volumes it is easier to hear the note at either end of the human hearing spectrum. So I play it loud, can hear the highs either, and that is why they bother me. This makes sense, but it seems that there still must be something else to it. I played the same track roughly 7dB louder (measured by SPL) at my house and the highs bothered me less at my house than at Marks.
