Hi Morgan. I have your kind of hearing issues, and highs that tend to the edgy, like produced by many "detailed" audiophile speakers, are hard on me. I got a bit of this when I heard the otherwise very nice Soul Superfly, and when I was seriously considering the Omen Def, Sean (who is very helpful), said he could address it with a modestly priced cap upgrade. I'm now very intrigued by the Def 4; I hope they bring them to RMAF.
