In my humble audio journey it seems like I identified some of the parts I like - the mids of HD650, the highs of MSR7, but I've yet to find the bass I like. I kinda thought it must be I'm not much of a basshead until recently I was in a blues concert and heard the bass I seem to enjoy - the kind that I felt left a void after each kick. If I understand the terms correctly, it was deep, fast, had a good kick, I think that's described as bass slam. On the contrary, the bass I seem to dislike is slow, boomy, if it bleeds into the mids, if it rumbles, too much mid bass (?). For example I didn't enjoy Fidelio X2, ATH M50 which are some of the most loved headphones in the community I found to have some of the disliked traits. Is such bass signature even possible in headphones? What would be examples of this within 1000EUR? Is anyone aware of a sound signature that would combine such bass with the things I liked of HD650/MSR7?
