Not exactly sure what you can still improve there for that kind of music.
Other headphones will likely be open back and depending on how much louder ambient noise is, even if it measures with more bass in a lab environment, outside of that you will perceive even less bass. That's counting adding an amplifier to make sure they can go loud without distortion to compensate for the likely lower sensitivity. Anything else these can give you - wider and deeper imaging, flatter response, etc - don't really matter for trance the way it's recorded (it's not like it's recorded in such a way that you can listen to how a piano's keys are laid out left to right, where the double bass is, where the guitar is, etc) nor for what you'd want to hear them do (ie bass will be as level as possible if not trail off sooner, effectively giving you waaaaaaaaaaaaaay less bass, even worse if it's an open back headphone).
If you just want more bass and hear much more of everything else louder and very clean, your best bet is probably the LCD-2C Closed back version. Drive it with something like a Schiit Lyr3 with the 4490 DAC card installed.
