I don't disagree, but I would caution against trying to iron out specific small peaks. Firstly,
small peaks are rarely audible; it's the overall frequency balance of a phone that determines its signature. Secondly, what shows up as small peaks in one trace may not show up in another taken under different conditions, or different peaks may show in different positions; it's not that exact a science. And what shows as peaks under measuring conditions may not be relevant to your ears, since the interaction of ears and phones is different for each individual. In short, I think to some degree you'll end up chasing your own tail.
Thanks for the advice. At the moment I'm just trying to turn down the treble with a graphic equalizer using the possible peaks as a guideline, I probably won't bother trying to equalize them completely w/ a PEQ. At the moment the cymbals are really annoying me. . .
