I think you're not used to very low distortion clean clear bass. You can try a much more powerful amp and it should get louder without clipping like you find with the e17, but clubs have very boomy bass with a lot of distortion and not a lot of texture..mostly just a ton of power that you can feel. It's not what good quality headphones like the HE-400 are designed to do..but I bet with a much more powerful amp you might be happy..
I just noticed something VERY odd regarding my previous gear and bass. I just put on a typical trance song with IE8's on my E17 NO eq and the bass is incredible, it's like they are reproducing a very accurate bass frequency response, tight deep, punch, very well defined.. something none of my headphones can do without a bass EQ
I'd need +8 bass (E17) on my xb700's to get the level of IE8's with no EQ and the bass knob on them isn't even on max.. the x1's probably need +4 or 6 to get the same amount and lastly he-400 can't even produce such intense bass at all on my e17... i wouldn't be surprised if the ie8s have the most accurate bass (with my setup) because after all I am playing trance songs, you'd expect to hear a strong bassline.. like something you'd hear with a decent set of 2.1 speakers, yet the headphones always cut short in that aspect, unless you boost them with an eq after an hour of testing I may have exaggerated, but the point remains the headphone usually need decent EQing to bring out the bass.. the he-400 with no bass eq is literally bassless in comparison
so if im an ultrabass head, then so is everyone that uses an IE8 with a decent source
I guess you won't really notice the inaccurate bass response (IMO) of the he-400s+E17 if you're not a trance/electro head.
