Since we've just had a discussion about eliminating ice pick highs, I figured I'd ask how to get the highs more filling and widespread (in lack of a better explanation). I sometimes feel they sound pretty thin. I think the amp's depth control may help, but then the low end is very affected as well. I'm using the USA LEAD and IIC+ amps, and to me it sounds like the IIC+ has a fuller high end, but I don't know. Also, as I'm using headphones I'm afraid that can be the whole issue. Does anyone else know what I'm talking about?
